Elliott Clark updated HBASE-14922: ---------------------------------- Component/s: regionserver > Delayed flush doesn't work causing flush storms. > ------------------------------------------------ > > Key: HBASE-14922 > URL: https://issues.apache.org/jira/browse/HBASE-14922 > Project: HBase > Issue Type: Bug > Components: regionserver > Affects Versions: 2.0.0, 1.2.0, 1.1.2 > Reporter: Elliott Clark > Assignee: Elliott Clark > Fix For: 2.0.0, 1.2.0, 1.3.0 > > Attachments: HBASE-14922-v1.patch, HBASE-14922.patch > > > Starting all regionservers at the same time will mean that most > PeriodicMemstoreFlusher's will be running at the same time. So all of these > threads will queue flushes at about the same time. > This was supposed to be mitigated by Delayed. However that isn't nearly > enough. This results in the immediate filling up and then draining of the > flush queues every hour. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
