Jean-Daniel Cryans commented on HBASE-6268:
-------------------------------------------
This is why I'm not a big fan of backports that are not simple-ish fixes...
So to me the most important would be to fix the 0.92 side as usually the
infrastructure in place will rely on the older version first. In our case we
started the migration of our clusters to 0.94 starting with the less important
ones so our tools are still relying on 0.92
> Can't enable a table on a 0.94 cluster from a 0.92 client

> In 0.92 we know a table's enabled by doing this in HCM.isEnabledTable:
> bq. return getTableState(zkw, tableName) == null;
> In 0.94 we do:
> bq. return getTableState(zkw, tableName) == TableState.ENABLED;
> So what happens is that the the 0.92 client will hang forever since the znode
> contains ENABLED instead of being absent.
