| <h1>Apache Kudu 1.1 Release Notes</h1> |
| <div class="sect1"> |
| <h2 id="rn_1.1.0_new_features"><a class="link" href="#rn_1.1.0_new_features">New features</a></h2> |
| <div class="sectionbody"> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>The Python client has been brought up to feature parity with the Java and C++ clients |
| and as such the package version will be brought to 1.1 with this release (from 0.3). A |
| list of the highlights can be found below.</p> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Improved Partial Row semantics</p> |
| </li> |
| <li> |
| <p>Range partition support</p> |
| </li> |
| <li> |
| <p>Scan Token API</p> |
| </li> |
| <li> |
| <p>Enhanced predicate support</p> |
| </li> |
| <li> |
| <p>Support for all Kudu data types (including a mapping of Python’s <code>datetime.datetime</code> to |
| <code>UNIXTIME_MICROS</code>)</p> |
| </li> |
| <li> |
| <p>Alter table support</p> |
| </li> |
| <li> |
| <p>Enabled Read at Snapshot for Scanners</p> |
| </li> |
| <li> |
| <p>Enabled Scanner Replica Selection</p> |
| </li> |
| <li> |
| <p>A few bug fixes for Python 3 in addition to various other improvements.</p> |
| </li> |
| </ul> |
| </div> |
| </li> |
| <li> |
| <p>IN LIST predicate pushdown support was added to allow optimized execution of filters which |
| match on a set of column values. Support for Spark, Map Reduce and Impala queries utilizing |
| IN LIST pushdown is not yet complete.</p> |
| </li> |
| <li> |
| <p>The Java client now features client-side request tracing in order to help troubleshoot timeouts. |
| Error messages are now augmented with traces that show which servers were contacted before the |
| timeout occured instead of just the last error. The traces also contain RPCs that were |
| required to fulfill the client’s request, such as contacting the master to discover a tablet’s |
| location. Note that the traces are not available for successful requests and are not |
| programatically queryable.</p> |
| </li> |
| </ul> |
| </div> |
| </div> |
| </div> |
| <div class="sect1"> |
| <h2 id="_optimizations_and_improvements"><a class="link" href="#_optimizations_and_improvements">Optimizations and improvements</a></h2> |
| <div class="sectionbody"> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Kudu now publishes JAR files for Spark 2.0 compiled with Scala 2.11 along with the |
| existing Spark 1.6 JAR compiled with Scala 2.10.</p> |
| </li> |
| <li> |
| <p>The Java client now allows configuring scanners to read from the closest replica instead of |
| the known leader replica. The default remains the latter. Use the relevant <code>ReplicaSelection</code> |
| enum with the scanner’s builder to change this behavior.</p> |
| </li> |
| <li> |
| <p>Tablet servers use a new policy for retaining write-ahead log (WAL) segments. |
| Previously, servers used the 'log_min_segments_to_retain' flag to prioritize |
| any flushes which were retaining log segments past the configured value (default 2). |
| This policy caused servers to flush in-memory data more frequently than necessary, |
| limiting write performance.</p> |
| <div class="paragraph"> |
| <p>The new policy introduces a new flag 'log_target_replay_size_mb' which |
| determines the threshold at which write-ahead log retention will prioritize flushes. |
| The new flag is considered experimental and users should not need to modify |
| its value.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The improved policy has been seen to improve write performance in some use cases |
| by a factor of 2x relative to the old policy.</p> |
| </div> |
| </li> |
| <li> |
| <p>Kudu’s implementation of the Raft consensus algorithm has been improved to include |
| a "pre-election" phase. This can improve the stability of tablet leader election |
| in high-load scenarios, especially if each server hosts a high number of tablets.</p> |
| </li> |
| <li> |
| <p>Tablet server start-up time has been substantially improved in the case that |
| the server contains a high number of tombstoned tablet replicas.</p> |
| </li> |
| </ul> |
| </div> |
| <div class="sect2"> |
| <h3 id="_command_line_tools"><a class="link" href="#_command_line_tools">Command line tools</a></h3> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>The tool <code>kudu tablet leader_step_down</code> has been added to manually force a leader to step down.</p> |
| </li> |
| <li> |
| <p>The tool <code>kudu remote_replica copy</code> has been added to manually copy a replica from |
| one running tablet server to another.</p> |
| </li> |
| <li> |
| <p>The tool <code>kudu local_replica delete</code> has been added to delete a replica of a tablet.</p> |
| </li> |
| <li> |
| <p>The <code>kudu test loadgen</code> tool has been added to replace the obsoleted |
| <code>insert-generated-rows</code> standalone binary. The new tool is enriched with |
| additional functionality and can be used to run load generation tests against |
| a Kudu cluster.</p> |
| </li> |

| <p>Kudu 1.1.0 is wire-compatible with previous versions of Kudu:</p> |

| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Kudu 1.1 clients may connect to servers running Kudu 1.0. If the client uses the new |

| <p>Rolling upgrade between Kudu 1.0 and Kudu 1.1 servers is believed to be possible |
| though has not been sufficiently tested. Users are encouraged to shut down all nodes |

| <div class="ulist"> |
| <ul> |
| <li> |
| <p>The C++ client no longer requires the |
| <a href="https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html">old gcc5 ABI</a>. |
| Which ABI is actually used depends on the compiler configuration. Some new distros |
| (e.g. Ubuntu 16.04) will use the new ABI. Your application must use the same ABI as is |
| used by the client library; an easy way to guarantee this is to use the same compiler |
| to build both.</p> |
| </li> |
| <li> |
| <p>The C++ client’s <code>KuduSession::CountBufferedOperations()</code> method is |
| deprecated. Its behavior is inconsistent unless the session runs in the |
| <code>MANUAL_FLUSH</code> mode. Instead, to get number of buffered operations, count |
| invocations of the <code>KuduSession::Apply()</code> method since last |
| <code>KuduSession::Flush()</code> call or, if using asynchronous flushing, since last |
| invocation of the callback passed into <code>KuduSession::FlushAsync()</code>.</p> |
| </li> |
| <li> |
| <p>The Java client’s <code>OperationResponse.getWriteTimestamp</code> method was renamed to <code>getWriteTimestampRaw</code> |
| to emphasize that it doesn’t return milliseconds, unlike what its Javadoc indicated. The renamed |
| method was also hidden from the public APIs and should not be used.</p> |
| </li> |
| <li> |
| <p>The Java client’s sync API (<code>KuduClient</code>, <code>KuduSession</code>, <code>KuduScanner</code>) used to throw either |
| a <code>NonRecoverableException</code> or a <code>TimeoutException</code> for a timeout, and now it’s only possible for the |
| client to throw the former.</p> |
| </li> |
| <li> |
| <p>The Java client’s handling of errors in <code>KuduSession</code> was modified so that subclasses of |
| <code>KuduException</code> are converted into RowErrors instead of being thrown.</p> |

| <p>Kudu is primarily designed for analytic use cases. You are likely to encounter issues if |
| a single row contains multiple kilobytes of data.</p> |
| </li> |
| <li> |
| <p>The columns which make up the primary key must be listed first in the schema.</p> |
| </li> |
| <li> |
| <p>Key columns cannot be altered. You must drop and recreate a table to change its keys.</p> |
| </li> |
| <li> |
| <p>Key columns must not be null.</p> |
| </li> |
| <li> |
| <p>Columns with <code>DOUBLE</code>, <code>FLOAT</code>, or <code>BOOL</code> types are not allowed as part of a |

| <h3 id="_impala_limitations"><a class="link" href="#_impala_limitations">Impala Limitations</a></h3> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>To use Kudu with Impala, you must install a special release of Impala called |
| Impala_Kudu. Obtaining and installing a compatible Impala release is detailed in Kudu’s |
| <a href="kudu_impala_integration.html">Impala Integration</a> documentation.</p> |
| </li> |
| <li> |
| <p>To use Impala_Kudu alongside an existing Impala instance, you must install using parcels.</p> |
| </li> |
| <li> |
| <p>Updates, inserts, and deletes via Impala are non-transactional. If a query |
| fails part of the way through, its partial effects will not be rolled back.</p> |
| </li> |
| <li> |
| <p>No timestamp and decimal type support.</p> |
| </li> |
| <li> |
| <p>The maximum parallelism of a single query is limited to the number of tablets |

| <div class="sect2"> |
| <h3 id="_other_known_issues"><a class="link" href="#_other_known_issues">Other Known Issues</a></h3> |
| <div class="paragraph"> |
| <p>The following are known bugs and issues with the current release of Kudu. They will |
| be addressed in later releases. Note that this list is not exhaustive, and is meant |
| to communicate only the most important known issues.</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>If the Kudu master is configured with the <code>-log_fsync_all</code> option, tablet servers |
| and clients will experience frequent timeouts, and the cluster may become unusable.</p> |
| </li> |
| <li> |
| <p>If a tablet server has a very large number of tablets, it may take several minutes |
| to start up. It is recommended to limit the number of tablets per server to 100 or fewer. |
| Consider this limitation when pre-splitting your tables. If you notice slow start-up times, |
| you can monitor the number of tablets per server in the web UI.</p> |
| </li> |
| <li> |
| <p>Due to a known bug in Linux kernels prior to 3.8, running Kudu on <code>ext4</code> mount points |
| may cause a subsequent <code>fsck</code> to fail with errors such as <code>Logical start <N> does |
| not match logical start <M> at next level</code>. These errors are repairable using <code>fsck -y</code>, |
| but may impact server restart time.</p> |
| <div class="paragraph"> |
| <p>This affects RHEL/CentOS 6.8 and below. A fix is planned for RHEL/CentOS 6.9. |
| RHEL 7.0 and higher are not affected. Ubuntu 14.04 and later are not affected. |
| SLES 12 and later are not affected.</p> |
