Hi, I ran a very simple rowcount (HBase) MR today, and one of the tasks failed with the status 126. Seems that there is no logs at all on the server side. Any idea what this mean?
Thanks, JM 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)
