Enis Soztutar commented on HBASE-12018:
---------------------------------------
HBASE-11983 is very relevant indeed. HRegion has two ways of being constructed,
and thus two ways of being closed. One way is to let HRegion create its own
hlog, and the other way is that it gets it in c.tor. In the former case,
HRegion.closeHRegion() should be used to close the region AND the log. In the
latter case, HRegion.close() should be used. I think the former way is only
used in tests, and we should actually get rid of this, and simplify it.
I think this patch is not applicable, since it closes the RS's logs when
closing a region. A region move will abort the RS I guess.
> HRegion.close neglects to close its HLog

> I found this while diagnosing leaking file handles after test runs in a build

> knowledgeable about region lifecycle can have a look.
