Subject [jira] [Created] (HDFS-9373) Show friendly information to user when client succeeds the writing with some failed streamers
Date Wed, 04 Nov 2015 09:36:27 GMT
Li Bo created HDFS-9373:
---------------------------

             Summary: Show friendly information to user when client succeeds the writing with
some failed streamers
                 Key: HDFS-9373
                 URL: https://issues.apache.org/jira/browse/HDFS-9373
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Li Bo
            Assignee: Li Bo


When not more than PARITY_NUM streamers fail for a block group, the client may still succeed
to write the data. But several exceptions are thrown to user and user has to check the reasons.
 The friendly way is just inform user that some streamers fail when writing a block group.
It’s not necessary to show the details of exceptions because a small number of stream failures
is not vital to the client writing.
