Subject Re: Wrong type in log history - Hadoop 0.21.0 (candidate 0)
Date Mon, 02 Aug 2010 03:52:54 GMT
The problem is reported and fixed in MAPREDUCE-1876, but it is not committed to branch 0.21.
I think both MAPREDUCE-1876 and MAPREDUCE-1980 should be committed to branch 0.21.

The log file produced in:

hadoop.job.history.location

Has a wrong type for "REDUCE_ATTEMPT_STARTED" (it is currently wrongly
printed as "MAP_ATTEMPT_STARTED").


This is one line of the log file produced:


{"type":"MAP_ATTEMPT_STARTED","event":{"TaskAttemptStarted":{"taskid":"task_201008010534_0001_r_000066","taskType":"REDUCE","attemptId":"attempt_201008010534_0001_r_000066_0","startTime":1280612215265,"trackerName":"tracker_compg3.cl.comp.nus.edu.sg:localhost.localdomain/127.0.0.1:37813","httpPort":38330}}},


Here, the type should be "REDUCE_ATTEMPT_STARTED", right? because the
"event.taskType" is "REDUCE".
