Hi,
I am seeing the below two errors consistently while running my map/reduce jobs.
This does not stop my script, but throws an error on datanode and successfully
completes the same task on a different datanode. The task could fail on any
datanode, there are no blacklisted datanodes.
Any thoughts on why this is and how can this be resolved ?
This is the whole stack;
java.lang.Throwable: Child Error
at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:472)
Caused by: java.io.IOException: Task process exit with nonzero status of 134.
at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:459)
Second Error: This is all it gives.
Error: null
Thanks for the support.
Regards
Syed Wasti
