Subject [jira] [Commented] (HBASE-7515) Store.loadStoreFiles should close opened files if there's an exception
Date Tue, 08 Jan 2013 21:24:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13547285#comment-13547285
] 

Jean-Daniel Cryans commented on HBASE-7515:
-------------------------------------------

bq. How about this one ?

The store file that threw the exception might still be opened, for example in HBASE-7513 it
opens fine but the exception is thrown in another part of the code. You might also be overwriting
{{ioe}}.

> 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".
