DataXceiver reads from client socket with incorrect/no timeout

      Description

      In DataXceiver, we currently use Socket.setSoTimeout to try to manage the read timeout when switching between reading the initial opCode, reading a keepalive opcode, and reading the status after a successfully sent block. However, since all of these reads use the same underlying DataInputStream, the change to the socket timeout isn't respected. Thus, they all occur with whatever timeout is set on the socket at the time of DataXceiver construction. In practice this turns out to be 0, which can cause infinitely hung xceivers.

          Attached patch depends on HADOOP-8350. It includes a regression test which fails without the patch and passes with it.

          It's worth pointing out that we now have a timeout for the non-cached case as well. This changes fixes two bugs: #1 that the setSoTimeout for the keepalive was a NOP, and #2 that there was no default timeout set on the socket given to DataXceiver. Perhaps DataXceiverServer could use a comment:

          s = ss.accept();
          s.setTcpNoDelay(true);
          + // DataXceiver sets the socket timeout
          

          Looks good, +1 pending jenkins

          doh... the tests passed when run in isolation but not when run together in a suite

          I had to add a "triggerHeartbeats" call after the DN restart in the test. Otherwise, the WRITE_BLOCK request was coming into the DN while it was in the process of starting up, which failed the write (this was just a test bug, nothing to do with the patch)

          Removing 1.1 from target versions. Although branch-1 does read the data xceiver header with no timeout, it doesn't really cause problems because branch-1 clients don't have the socket cache (HDFS-941). So I don't think there's any strong reason to do the fix. If others disagree, I'm happy to review a patch, though.
