> ReplicationMonitor thread could stuck for long time and loss data with little
> probability. Consider the typical scenarioļ¼
> (1) create and close a file with the default replicas(3);
> (2) increase replication (to 10) of the file.
> (3) delete the file while ReplicationMonitor is scheduling blocks belong to
> that file for replications.
> if ReplicationMonitor stuck reappeared, NameNode will print log as:

> This is because 2 threads (#NameNodeRpcServer and #ReplicationMonitor)
> process same block at the same moment.
> (1) ReplicationMonitor#computeReplicationWorkForBlocks get blocks to
> replicate and leave the global lock.
> (2) FSNamesystem#delete invoked to delete blocks then clear the reference in
> blocksmap, needReplications, etc. the block's NumBytes will set
> NO_ACK(Long.MAX_VALUE) which is used to indicate that the block deletion does
> not need explicit ACK from the node.
> (3) ReplicationMonitor#computeReplicationWorkForBlocks continue to
> chooseTargets for the same blocks and no node will be selected after traverse
> whole cluster because no node choice satisfy the goodness criteria
> (remaining spaces achieve required size Long.MAX_VALUE).
> During of stage#3 ReplicationMonitor stuck for long time, especial in a large
> cluster. invalidateBlocks & neededReplications continues to grow and no
> consumes. it will loss data at the worst.
> This can mostly be avoided by skip chooseTarget for BlockCommand.NO_ACK block
> and remove it from neededReplications.
