ruanhui updated HBASE-26716:
----------------------------
Description:
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 are case insensitive. This will make
org.apache.hadoop.hbase.util.TestRegionMoverWithRSGroupEnable fail.
