hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java Change parameter name and add javadoc to make it more clear what the param actually is. hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/handler/AssignRegionHandler.java Move postOpenDeployTasks so if it fails to talk to the Master -- which can happen on cluster shutdown -- then we will do cleanup of state; without this the RS can get stuck and won't go down. hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/handler/CloseRegionHandler.java Add handleException so CRH looks more like UnassignRegionHandler and AssignRegionHandler around exception handling. Add a bit of doc on why CRH. hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/handler/UnassignRegionHandler.java Right shift most of the body of process so can add in a finally that cleans up rs.getRegionsInTransitionInRS is on exception (otherwise outstanding entries can stop a RS going down on cluster shutdown) Signed-off-by: Nick Dimiduk <ndimiduk@apache.org> Signed-off-by: Duo Zhang <zhangduo@apache.org>
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.
