Subject [jira] [Created] (HDFS-6996) SnapshotDiff report can hit IndexOutOfBoundsException when there are nested renamed directory/file
Date Thu, 04 Sep 2014 20:12:23 GMT
Jing Zhao created HDFS-6996:
-------------------------------

             Summary: SnapshotDiff report can hit IndexOutOfBoundsException when there are
nested renamed directory/file
                 Key: HDFS-6996
                 URL: https://issues.apache.org/jira/browse/HDFS-6996
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: snapshots
    Affects Versions: 2.5.0
            Reporter: Jing Zhao
            Assignee: Jing Zhao


Currently when computing snapshot diff report where a renamed file/directory is involved,
we scan the {{withNameList}} inside of the corresponding WithCount node to identify the correct
rename target. However, the {{withNameList}} can be empty due to snapshot deletion operations
thus an IndexOutOfBoundsException can be triggered.
