> Cluster setup:
> 1NN,Three DN(DN1,DN2,DN3),replication factor-2,"dfs.blockreport.intervalMsec"
> 300,"dfs.datanode.directoryscan.interval" 1
> step 1: write one file "a.txt" with sync(not closed)
> step 2: Delete the blocks in one of the datanode say DN1(from rbw) to which
> replication happened.
> step 3: close the file.
> Since the replication factor is 2 the blocks are replicated to the other
> datanode.
> Then at the NN side the following cmd is issued to DN from which the block is
> deleted
