Bochun Bai commented on HBASE-4180:
-----------------------------------
0.20 doesn't have isSecurityEnabled,
0.20-SEC does have isSecurityEnabled,
0.21 does have isSecurityEnabled but not means it must configured to use it.
If we need HBase work with a non-security hadoop, I think we need find another
way to identify it.
> HBase should check the isSecurityEnabled flag
