> MiniDFSCluster#shouldWait() method waits for all the datanodes to come up and
> register with the namenode.
> Due to threading issues some of the tests fail for two reasons:
> # Datanode#isDatanodeUp() fails even if all the BPOfferService threads have
> exited. This is due to Thread.isAlive()
> returning true, even though the thread has exited. Adding a check to
> BPOfferService#shouldService run as an addition,
> fixes this issues.
> # shouldWait(), where isBPServiceAlive() is called, does not work when a
> BPOfferService thread fails before the
> datanode has discovered the BPID, from handshake with namenode. This can be
> fixed by checking the thread state using
> InetSocketAddress to determine the BPOfferService, instead of BPID.
