On failed RPC we expire the server and suspend expecting the resultant ServerCrashProcedure to wake us back up again. In tests, TestRSGroup hung because it failed to schedule a server expiration because the server was already expired undergoing processing (the test was shutting down). Deal with this case by having expire servers return false if unable to expire. Callers will then know where a ServerCrashProcedure has been scheduled or not. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/ServerManager.java Have expireServer return true if successful. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionTransitionProcedure.java The log that included an exception whose message was the current procedure as a String totally baffled me. Make it more obvious what exception is. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/UnassignProcedure.java If failed expire of a server, wake our procedure -- do not suspend -- and presume ok to move region to CLOSED state (because going down or concurrent crashed server processing ongoing). |

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.
