Hi, Could anyone point me to a summary on why this error would occur?
java.lang.Throwable: Child Error at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:471) Caused by: java.io.IOException: Task process exit with nonzero status of 1. at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:458) I know of the following two reasons. 1) Insufficient space in the logs directory 2) ulimit threshold that causes insuffucient allocation of memory. Thanks Sudharsan S
