[jira] [Commented] (HBASE-6469) Failure on enable/disable table
will cause table state in zk to be left as enabling/disabling until master
is restarted

-----------------------------------------------
I have similar concern as Lars has. Infact if you see latest changes N and others are trying to remove this timing mechanisms. So introducing such a thing will not welcomed.
Lets see what others say and check this out.

> 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.
