-------------------------------
Assignee: ruanhui
> NPE caused by converting uppercase hostname to lowercase in RegionMover
> -----------------------------------------------------------------------
>
> Key: HBASE-26716
> URL: https://issues.apache.org/jira/browse/HBASE-26716
> Project: HBase
> Issue Type: Bug
> Components: util
> Affects Versions: 2.4.9
> Reporter: ruanhui
> Assignee: ruanhui
> Priority: Minor
>
> In HBASE-19456, we introduced case-insensitivity feature in RegionMover and
> converted uppercase hostnames to lowercase hostnames. But this maybe causes
> that we can't get the rsgroup info of unloading server, because the addresses
> in hbase case insensitive. This will make
> org.apache.hadoop.hbase.util.TestRegionMoverWithRSGroupEnable fail.
