Dima Spivak commented on HBASE-16222:
-------------------------------------
According to RFC 4343,
bq. comparisons on name lookup for DNS queries should be case insensitive.
As such, might it be more correct to make any hostname comparisons case
insensitive?
> RegionServer hostName is different between zk and hbase:meta

> I migrated rs-group in 1.1.2version,and found regionserver host is different
> between zk and meta table.
> For example, host BeiJIN.98.100.hbase.com In zk or master is
> beijin.98.100.hbase.com , but in meter table is BeiJIN.98.199.hbase.com.
> Because of this , when rsgroup balance compare host , that cause problem 。
> And i found when regionserver report host to master , it will make the
> hostname to lowcase。
