Lars Hofhansl commented on HBASE-12457: --------------------------------------- Unfortunately there is not API to interrupt all threads in a Threadpool without shutting down the pool. > Regions in transition for a long time when CLOSE interleaves with a slow > compaction > ----------------------------------------------------------------------------------- > > Key: HBASE-12457 > URL: https://issues.apache.org/jira/browse/HBASE-12457 > Project: HBase > Issue Type: Bug > Affects Versions: 0.98.7 > Reporter: Lars Hofhansl > Attachments: 12457-minifix.txt > > > Under heave load we have observed regions remaining in transition for 20 > minutes when the master requests a close while a slow compaction is running. > The pattern is always something like this: > # RS starts a compaction > # HM request the region to be closed on this RS > # Compaction is not aborted for another 20 minutes > # The region is in transition and not usable. > In every case I tracked down so far the time between the requested CLOSE and > abort of the compaction is almost exactly 20 minutes, which is suspicious. > Of course part of the issue is having compactions that take over 20 minutes, > but maybe we can do better here. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
