Exception in createBlockOutputStream

I am running apache hadoop 5 node cluster. Earlier it is working fine but
now when i use -copyFromLocal command then it gives following error:

5/05/14 16:53:16 INFO hdfs.DFSClient: Exception in createBlockOutputStream
java.io.IOException: Bad connect ack with firstBadLink as 172.17.14.11:50010

Firewall is turned off and also set dfs.datanode.max.xcievers in
hdfs-site.xml but still getting same error. Any help will be highly
appreciated.
