Master force-closes unknown/incorrect Regions OPEN on RS M hbase-client/src/main/java/org/apache/hadoop/hbase/MetaTableAccessor.java Added a note and small refactor. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/CatalogJanitor.java Fix an NPE when CJ ran. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java Minor clean up of log message; make it clearer. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/ServerManager.java Make it so closeRegionSilentlyAndWait can be used w/o timeout. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java If a RegionServer Report notes a Region is OPEN and the Master does not know of said Region, close it (We used to crash out the RegionServer) M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionStateNode.java Minor tweak of toString -- label should be state, not rit (confusing). M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionStates.java Doc. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/TransitRegionStateProcedure.java Add region name to exception. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/HBCKServerCrashProcedure.java Be more careful about which Regions we queue up for reassign. This procedure is run by the operator so could happen at any time. We will likely be running this when Master has some accounting of cluster members so check its answers for what Regions were on server before running. M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java Doc and we were misrepresenting the case where a Region as not in RIT when we got CLOSE -- we were reporting it as though it was already trying to CLOSE. |

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.
