Found this almost a year old discussion, on the same error code and it looks like a JVM crash. The discussion confirms the crash on JDK 14 and I am using JDK version 18.

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 Third Error: Error: (class: org/apache/pig/builtin/PigStorage, method: setLocation signature: (Ljava/lang/String;Lorg/apache/hadoop/mapreduce/Job;)V) Thanks for the support. Regards Syed Wasti
