Patch to start a standalone RegionServer that register's itself and optionally stands up Services. Can work w/o a Master in the mix. Useful testing. Also can be used by hbase-indexer to put up a Replication sink that extends public-facing APIs w/o need to extend internals. See JIRA release note for detail. This patch adds booleans for whether to start Admin and Client Service. Other refactoring moves all thread and service start into the one fat location so we can ask to by-pass 'services' if we don't need them. See JIRA for an example hbase-server.xml that has config to shutdown WAL, cache, etc. Adds checks if a service/thread has been setup before going to use it. Renames the ExecutorService in HRegionServer from service to executorService. See JIRA too for example Connection implementation that makes use of Connection plugin point to receive a replication stream. The default replication sink catches the incoming replication stream, undoes the WALEdits and then creates a Table to call a batch with the edits; up on JIRA, an example Connection plugin (legit, supported) returns a Table with an overridden batch method where in we do index inserts returning appropriate results to keep the replication engine ticking over. Upsides: an unadulterated RegionServer that will keep replication metrics and even hosts a web UI if wanted. No hacks. Just ordained configs shutting down unused services. Injection of the indexing function at a blessed point with no pollution by hbase internals; only public imports. No user of Private nor LimitedPrivate classes. |

Apache HBase [1] is an open-source, distributed, versioned, column-oriented store modeled after Google' Bigtable: A Distributed Storage System for Structured Data by Chang et al.[2] Just as Bigtable leverages the distributed data storage provided by the Google File System, HBase provides Bigtable-like capabilities on top of Apache Hadoop [3]. To get started using HBase, the full documentation for this release can be found under the doc/ directory that accompanies this README. Using a browser, open the docs/index.html to view the project home page (or browse to [1]). The hbase 'book' at http://hbase.apache.org/book.html has a 'quick start' section and is where you should being your exploration of the hbase project. The latest HBase can be downloaded from an Apache Mirror [4]. The source code can be found at [5] The HBase issue tracker is at [6] Apache HBase is made available under the Apache License, version 2.0 [7] The HBase mailing lists and archives are listed here [8]. The HBase distribution includes cryptographic software.
