Allow HBase coprocessors to clean up when they fail (Benoit Sigoure) (apurtell: rev 1550030) * /hbase/branches/0.94/src/main/java/org/apache/hadoop/hbase/coprocessor/CoprocessorHost.java > Allow HBase coprocessors to clean up when they fail > --------------------------------------------------- > > Key: HBASE-10119 > URL: https://issues.apache.org/jira/browse/HBASE-10119 > Project: HBase > Issue Type: New Feature > Affects Versions: 0.96.0 > Reporter: Benoit Sigoure > Assignee: Benoit Sigoure > Fix For: 0.98.0, 0.96.1, 0.94.15, 0.99.0 > > Attachments: HBASE-10119-0.94.patch, HBASE-10119.patch > > > In the thread [Giving a chance to buggy coprocessors to clean up|http://osdir.com/ml/general/2013-12/msg17334.html] I brought up the issue that coprocessors currently don't have a chance to release their own resources (be they internal resources within the JVM, or external resources elsewhere) when they get forcefully removed due to an uncaught exception escaping. > It would be nice to fix that, either by adding an API called by the {{CoprocessorHost}} when killing a faulty coprocessor, or by guaranteeing that the coprocessor's {{stop()}} method will be invoked then. > This feature request is actually pretty important due to bug HBASE-9046, which means that it's not possible to properly clean up a coprocessor without restarting the RegionServer (!!). -- This message was sent by Atlassian JIRA (v6.1.4#6159)
