Subject [jira] [Commented] (MAPREDUCE-5612) Document TaskAttemptCompletionEventStatuses
Date Wed, 25 Feb 2015 20:39:05 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14337132#comment-14337132
] 

Akira AJISAKA commented on MAPREDUCE-5612:
------------------------------------------

Thanks [~pvs013] for creating the patch. Some comments:
1. Could you add the Jason's comment
bq.  When a reducer receives a TIPFAILED event it gives up trying to shuffle data from that
map task.
to the javadoc for {{TIPFAILED}}?
2. Would you please add the document to o.a.h.*mapreduce*.TaskCompletionEvent.java also?
3. Some lines are longer than 80 characters, so would you render the lines within 80 characters?
4. The below semicolon is unnecessarily.
{code}
+    TIPFAILED
+ };
{code}
