> In Enable/DisableTableHandler code, if something goes wrong in handling, the table state
in zk is left as ENABLING / DISABLING. After that we cannot force any more action from the
API or CLI, and the only recovery path is restarting the master. 
> {code}
>     if (done) {
>       // Flip the table to enabled.
>       this.assignmentManager.getZKTable().setEnabledTable(
>         this.tableNameStr);
>       LOG.info("Table '" + this.tableNameStr
>       + "' was successfully enabled. Status: done=" + done);
>     } else {
>       LOG.warn("Table '" + this.tableNameStr
>       + "' wasn't successfully enabled. Status: done=" + done);
>     }
> {code}
> Here, if done is false, the table state is not changed. There is also no way to set skipTableStateCheck
from cli / api. 
> We have run into this issue a couple of times before.
