Subject [jira] [Updated] (HBASE-6469) Failure on enable/disable table will cause table state in zk to be left as enabling/disabling until master is restart
Date Thu, 06 Dec 2012 22:05:10 GMT

     [ https://issues.apache.org/jira/browse/HBASE-6469?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Nick Dimiduk updated HBASE-6469:
--------------------------------

    Attachment: 6469-expose-force.patch

This completes the patch started in [review 8333|https://reviews.apache.org/r/8333/]. It exposes
a new "force" option to the table enable and disable operators in the AdminMasterProtocol.
It also updates the existing TestAdmin coverage of the enable and disable paths.

Most of the change is serialization noise. The new work happens in the two Handler classes.

> 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.
