          Description

          When testing the tail'ing of a local file with the read short circuit on, I get:

            Ah turns out I can read the file, just not the block on the local machine (the "Try reading via the datanode on" didn't lie as I originally thought).

            so is this still a bug or can it be closed as invalid?

            Suresh, I changed the title to reflect what I think is really the issue, and yes this is a bad bug.

            Another failure mode is when the block is done being written to (block unrelated with the one in the description):

            I still don't understand what's the length mismatch here, but one way we can fix this is by not using the BlockReaderLocal when the block is being written to. This is a 2 lines change which I'm attaching here. I tested it on a single node and it works, I'm about to deploy on a few clusters.

            I guess I was tired when I did the other patch and missed the refactoring opportunity, attaching new version against branch-1.

            We've been running with my patch in production for 2 weeks now on a few hundred nodes with HBase doing reads on local files that are still being written to. Everything looks good.

            Attaching trunk's version. It's been a while since I've been in trunk so apologies if I did anything wrong.

            It seems the input stream was moved out of DFSClient so I had to do some massaging. Basically I'm trying to keep shouldTryShortCircuitRead the same way I changed it for branch-1 but now the check is done in DFSInputStream.

            I thought both findbugs warnings were bogus but actually the 2nd one is due to this patch. The access to locatedBlocks needs to be synchronized, in practice it should be fine, but findbugs complains because all other accesses are synchronized. I pulled your check out to a private synchronized method. Updated patch attached.
