Description

Currently HBaseAdmin#isTableRepEnabled() returns false if ANY of the columns families is not replicated.

Because of this if you have a table where replication is partially enabled, calling disable_table_replication will not have any effect, but will report that replication for a given table is disabled.

Workaround is enabling table replication before disabling.

As a solution quoted from HBASE-17460:
Admin#disableTableReplication() returns nothing and isTableRepEnabled() returns boolean. For master branch, we can let isTableRepEnabled() return enum (partially disabled, disabled, etc) This way, Admin#disableTableReplication() can return meaningful value to the user.
