Jeffrey Zhong created HBASE-10895: ------------------------------------- Summary: unassign a region fails due to the hosting region server is in FailedServerList Key: HBASE-10895 URL: https://issues.apache.org/jira/browse/HBASE-10895 Project: HBase Issue Type: Bug Components: Region Assignment Affects Versions: 0.98.1, 0.96.1, 0.99.0 Reporter: Jeffrey Zhong Assignee: Jeffrey Zhong
This issue is similar as HBASE-10833 which deal with the sendRegionOpen RPC while the JIRA issue happens with sendRegionClose. Once a RS in in failed server list due to a network hiccup, AM quickly exhausted all retries and failed the whole region assignment later.
