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

                 Key: HDFS-504
                 URL: https://issues.apache.org/jira/browse/HDFS-504
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
    Affects Versions: 0.20.1
            Reporter: Chun Zhang
            Priority: Minor
             Fix For: 0.20.1


HDFS updates the modification time of a file when the file is created. We would like to update
the modification time of the file when the file is closed after being written to. This helps
HDFS Raid to detect file changes more aggressively.

Solution includes:
1. Made changes to closeFile@/org/apache/hadoop/hdfs/server/namenode/FSDirectory.java;
2. Added unit test to testTimesAtClose@/org/apache/hadoop/hdfs/TestSetTimes.java.
