Ted Yu commented on HBASE-7515:
-------------------------------
I looked at storeFile.createReader call. My understanding is that the exception
from the Callable would be delivered when get() is called.
Please take a look at the example in:
http://docs.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/ExecutorCompletionService.html
> Store.loadStoreFiles should close opened files if there's an exception

> 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".
