| Description: Apache Accumulo is a highly scalable structured store based on Google’s BigTable. |
| Accumulo is written in Java and operates over the Hadoop Distributed File |
| System (HDFS), which is part of the popular Apache Hadoop project. Accumulo |
| supports efficient storage and retrieval of structured data, including queries |
| for ranges, and provides support for using Accumulo tables as input and output |
| for MapReduce jobs. Accumulo features automatic load-balancing and |
| partitioning, data compression and fine-grained security labels. |

| |
| Package: accumulo-master |
| Architecture: all |
| Depends: accumulo (= ${source:Version}) |
| Description: The Accumulo Master server. |
| The Accumulo Master is responsible for detecting and responding to TabletServer |
| failure. It tries to balance the load across TabletServer by assigning tablets |
| carefully and instructing TabletServers to unload tablets when necessary. The |
| Master ensures all tablets are assigned to one TabletServer each, and handles |
| table creation, alteration, and deletion requests from clients. The Master also |
| coordinates startup, graceful shutdown and recovery of changes in write-ahead |
| logs when Tablet servers fail. Multiple masters may be run. The masters will |
| choose among themselves a single master, and the others will become backups if |
| the master should fail. |
| |
| Package: accumulo-tserver |
| Architecture: all |
| Depends: accumulo (= ${source:Version}) |
| Description: The Accumulo TabletServer daemon |
| The TabletServer manages some subset of all the tablets (partitions of tables). |
| This includes receiving writes from clients, persisting writes to a write-ahead |
| log, sorting new key-value pairs in memory, periodically flushing sorted key- |
| value pairs to new files in HDFS, and responding to reads from clients, forming |
| a merge-sorted view of all keys and values from all the files it has created |
| and the sorted in-memory store. TabletServers also perform recovery of a tablet |
| that was previously on a server that failed, reapplying any writes found in the |
| write-ahead log to the tablet. |
| |
| Package: accumulo-gc |
| Architecture: all |
| Depends: accumulo (= ${source:Version}) |
| Description: The Accumulo Garbage Collector daemon |
| Accumulo processes will share files stored in HDFS. Periodically, the Garbage |
| Collector will identify files that are no longer needed by any process, and |
| delete them. |
| |
| Package: accumulo-monitor |
| Architecture: all |
| Depends: accumulo (= ${source:Version}) |
| Description: The Accumulo Monitor daemon |
| The Monitor serves as a log aggregation point for the other servers and |
| provides a web UI for basic monitoring. |
| |
| Package: accumulo-tracer |
| Architecture: all |
| Depends: accumulo (= ${source:Version}) |
| Description: The Accumulo Tracer daemon |
| The Tracer does distributed profiling of runtime performance. profiling of |
| low-level internal operations always happens, and users may optionally turn |
| on more comprehensive profiling on a per-table basis. |
