---------------------------------

             Summary: Consider attaching block location info from client when closing a completed file
                 Key: HDFS-16569
                 URL: https://issues.apache.org/jira/browse/HDFS-16569
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Yuanbo Liu


when a file is finished, client will not close it until DNs send RECEIVED_BLOCK by ibr or client is timeout. we can always see such kind of log in namenode
{code:java}
is COMMITTED but not COMPLETE(numNodes= 0 <  minimum = 1) in file{code}
Since client already has the last block locations, it's not necessary to rely on the ibr from DN when closing file.
