Subject [jira] Commented: (HADOOP-4716) testRestartWithLostTracker frequently times out
Date Wed, 26 Nov 2008 06:10:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4716?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12650870#action_12650870

Amar Kamat commented on HADOOP-4716:
------------------------------------

Johan, it might look like the line
{code}
[exec] [junit] 2008-11-23 08:19:01,944 INFO mapred.TaskTracker (TaskTracker.java:reportProgress(1898))
- 
  attempt_200811230815_0001_r_000000_0 0.10666667% reduce > copy (16 of 50 at 0.00 MB/s)
>
{code}
is in a loop but if you observe the part 
{code}
copy (16 of 50 at 0.00 MB/s)
      ^^
{code}
you will see that the number (marked with ^^) keeps on changing. The job runs 50 map tasks
and hence the reducer copies 50 maps outputs.  Let me know if this is not the case. I ran
this test on my box and it passed. I will run it in a loop to see if I can reproduce this.
Can you attach the logs for this test?
