Yuanbo Liu created HDFS-16569:
---------------------------------
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.
