> Steps to Repro :
> 1. Start writing a EC file.
> 2. After more than one stripe has been written, stop one datanode.
> 3. Post pipeline recovery, keep on writing the data.
> 4.Close the file.
> 5. transition the namenode to standby and back to active.
> 6. Turn on the shutdown datanode in step 2
> The BR from datanode 2 will make the block corrupt and during invalidate
> block won't remove it, since post failover the blocks would be on stale
> storage.
