> 1)Batch IBR is enabled with number of committed blocks allowed=1
> 2) Written one block and closed the file without waiting for IBR
> 3)Setreplication called immediately on the file. 
> So till the finalized IBR Received, block will not be added to {{neededReconstruction}} since following check will be {{false}} as block is not marked as complete.
> {code}
> if (isNeededReconstruction(block, repl.liveReplicas())) {
>         neededReconstruction.update(block, repl.liveReplicas(),
>             repl.readOnlyReplicas(), repl.decommissionedAndDecommissioning(),
>             curExpectedReplicas, curReplicasDelta, expectedReplicasDelta);
>       }.{code}
> Hence block will not marked as under-replicated.
