Subject [jira] [Commented] (HBASE-3692) Handle RejectedExecutionException in HTable
Date Mon, 19 Mar 2012 23:57:37 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3692?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13233037#comment-13233037
] 

Lars Hofhansl commented on HBASE-3692:
--------------------------------------

In 0.92 you can also use HBASE-4805. It let's you create an HConnection and ExecutorService
separately and pass them to the HTable constructor.

> A user on IRC yesterday had an issue with RejectedExecutionException coming out of HTable
sometimes. Apart from being very confusing to the user as it comes with no message at all,
it exposes the HTable internals. 
> I think we should handle it and instead throw something like DontUseHTableInMultipleThreadsException
or something more clever. In his case, the user had a HTable leak with the pool that he was
able to figure out once I told him what to look for.
> It could be an unchecked exception and we could consider adding in 0.90 but marking for
0.92 at the moment.
