Mac Yang updated HADOOP-2403:
-----------------------------
Priority: Critical (was: Major)
Description:
When some tasks failed, the job tracker writes an line to the history file with
error message.
However, the error message may mess up with the history file format, choking
the history parser. Here is an example:
MapAttempt TASK_TYPE="MAP" TASKID="tip_200712102254_0001_m_000090"
TASK_ATTEMPT_ID="task_200712102254_0001_m_000090_0" TASK_STATUS="FAILED"
FINISH_TIME="1197327293253" HOSTNAME="XXXX:50050"
ERROR="java.lang.IllegalArgumentException: Trouble to get key or value (<,>
substituted by null
. Key XML-Ori:
<Root>
