Mikhail Antonov commented on HBASE-11108:
-----------------------------------------

Test failures look unrelated. TestHCM (passes on my local) fails with the same 
multicast issue on JDK 7 which has already been pointed out today..

{code}
Caused by: java.lang.UnsupportedOperationException: Only supported on java 7+.

> In HBASE-11071 we are trying to split admin handlers away from ZK. However, a 
> ZKTable instance is being used in multiple places, hence it would be 
> beneficial to hide its implementation behind a well defined interface.
