Subject [jira] [Created] (HDFS-8658) Improve retry attempt log in DFSOutputStream#completeFile with current attempt number
Date Wed, 24 Jun 2015 12:24:05 GMT
kanaka kumar avvaru created HDFS-8658:
-----------------------------------------

             Summary: Improve retry attempt log in DFSOutputStream#completeFile  with current
attempt number
                 Key: HDFS-8658
                 URL: https://issues.apache.org/jira/browse/HDFS-8658
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: kanaka kumar avvaru
            Assignee: kanaka kumar avvaru
            Priority: Minor


In a scenario when block update was delayed from DN to NN, following client log is observed
which is confusing that file close failed after two attempts but it tried 5 times actually.
So, it's better to log the current and remaining attempt counts.

{code}
15/06/23 17:05:10 INFO hdfs.DFSClient: Could not complete /write2/tst5484._COPYING_ retrying...
15/06/23 17:05:16 INFO hdfs.DFSClient: Could not complete /write2/tst5484._COPYING_ retrying...
copyFromLocal: Unable to close file because the last block does not have enough number of
replicas.
