Anything in TaskTracker logs ?
Actually I've found something like this in jobs log. When running
wordcount I got it in a file:
${result_dir}/_logs/history/job_201201311241_0008_1328055139152_hdfs_word+count
MapAttempt TASK_TYPE="SETUP" TASKID="task_201201311241_0008_m_000001"
TASK_ATTEMPT_ID="attempt_201201311241_0008_m_000001_0"
TASK_STATUS="FAILED" FINISH_TIME="1328049504887" HOSTNAME="hadoop2"
ERROR="Error: Could not initialize class org\.apache\.log4j\.LogManager"
.
I'm especially worried about this "Could not initialize class" error.
Could it be related to the missing log.index file?
