Subject [jira] [Commented] (HBASE-7515) Store.loadStoreFiles should close opened files if there's an exception
Date Wed, 09 Jan 2013 17:26:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13548696#comment-13548696
] 

ramkrishna.s.vasudevan commented on HBASE-7515:
-----------------------------------------------

+1 on V5.
@Chunhui
What specific difference we will get between v4 and v5?
Anyway in v4 do we try to close the reader if open fails?  May be we can just throw exception
alone.

> Related to HBASE-7513. If a RS is able to open a few store files in {{Store.loadStoreFiles}}
but one of them fails like in 7513, the opened files won't be closed and file descriptors
will remain in a CLOSED_WAIT state.
> The situation we encountered is that over the weekend one region was bounced between
>100 region servers and eventually they all started dying on "Too many open files".
