Hi everybody, I am facing a problem after I ran a 2TB data. It says the job is completed but there are 4 failed tasks. Here is the information: java.lang.Throwable: Child Error at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:271) Caused by: java.io.IOException: Task process exit with nonzero status of 126. at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:258)
Does anybody know the reason? Thank you very much!
