<h1 class="entry-title">Apache Kudu 1.11.1 released</h1>
<p class="meta">Posted 20 Nov 2019 by Alexey Serbin</p>
<div class="entry-content">
<p>The Apache Kudu team is happy to announce the release of Kudu 1.11.1!</p>
<p>This release contains a fix which addresses a critical issue discovered in
1.10.0 and 1.11.0 and adds several new features and improvements since 1.10.0.</p>
<p>Apache Kudu 1.11.1 is a bug fix release which fixes critical issues discovered
in Apache Kudu 1.11.0. In particular, this release fixes a licensing issue with
distributing libnuma library with the kudu-binary JAR artifact. Users of
Kudu 1.11.0 are encouraged to upgrade to 1.11.1 as soon as possible.</p>
<p>Apache Kudu 1.11.1 adds several new features and improvements since
Apache Kudu 1.10.0, including the following:</p>
<li>Kudu now supports putting tablet servers into maintenance mode: while in this
mode, the tablet server’s replicas will not be re-replicated if the server
fails. Administrative CLI are added to orchestrate tablet server maintenance
(see <a href="">KUDU-2069</a>).</li>
<li>Kudu now has a built-in NTP client which maintains the internal wallclock
time used for generation of HybridTime timestamps. When enabled, system clock
synchronization for nodes running Kudu is no longer necessary,
(see <a href="">KUDU-2935</a>).</li>
<li>Aggregated table statistics are now available to Kudu clients. This allows
for various query optimizations. For example, Spark now uses it to perform
join optimizations
(see <a href="">KUDU-2797</a> and
<a href="">KUDU-2721</a>).</li>
<li>The kudu CLI tool now supports creating and dropping range partitions
for a table
(see <a href="">KUDU-2881</a>).</li>
<li>The kudu CLI tool now supports altering and dropping table columns.</li>
<li>The kudu CLI tool now supports getting and setting extra configuration
properties for a table
(see <a href="">KUDU-2514</a>).</li>
<p>See the <a href="/releases/1.11.1/docs/release_notes.html">release notes</a> for details.</p>
<p>The Apache Kudu project only publishes source code releases. To build Kudu
1.11.1, follow these steps:</p>
<li>Download the Kudu <a href="/releases/1.11.1">1.11.1 source release</a></li>
<li>Follow the instructions in the documentation to build Kudu <a href="/releases/1.11.1/docs/installation.html#build_from_source">1.11.1 from
<p>For your convenience, binary JAR files for the Kudu Java client library, Spark
DataSource, Flume sink, and other Java integrations are published to the ASF
Maven repository and are <a href="">now
<p>The Python client source is also available on
<a href="">PyPI</a>.</p>
<p>Additionally experimental Docker images are published to
<a href="">Docker Hub</a>.</p>
