Description
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. Below is a sample stack trace:
