[jira] [Commented] (HBASE-20552) HBase RegionServer was shutdown
due to UnexpectedStateException
[ https://issues.apache.org/jira/browse/HBASE-20552?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17147512#comment-17147512 ]
shenshengli commented on HBASE-20552:
-------------------------------------
I reproduced the problem in my own environment, with more than 10,000 regions on each RS.By adjusting the parameters of ’hbase.regionserver.msginterval‘, it from 3 s and 30 s, greatly reduces the risk of the problem.Conversely, if you go from 3s down to below 1s, this is almost certainly going to happen.
