> 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.
