Yongjun Zhang created HDFS-6499:
-----------------------------------

             Summary: can't tell why FileJournalManager's call to java.io.File.renameTo()
fails
                 Key: HDFS-6499
                 URL: https://issues.apache.org/jira/browse/HDFS-6499
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
    Affects Versions: 2.4.0
            Reporter: Yongjun Zhang
            Assignee: Yongjun Zhang


java.io.File's method renameTo()  returns boolean (true for success and false for failure).
If any call to this method failed, the caller can't tell why it failed.

Filing this jira to address this issue by using hadoop nativeio alternative.
