Datanode decommision hungs



I am trying to decommision one of my datanode and the decom process is running for long time moving blocks.

now it moved almost all blocks, but could see its finding difficult to move last 7 blocks.

When checked the namenode UI, it states

Under Replicated Blocks In files under construction 


 This value is not getting reduced to 0.


dfs admin report states, no under replicated blocks in the cluster

Any thing i can do now to fix this and make this datanode to decommision ?

Many Thanks in advance.
