I've been getting the following error in several cases:
2017-03-23 11:55:10,794 INFO [AsyncDispatcher event handler] org.apache.hadoop.mapreduce.v2.app.job.impl.TaskAttemptImpl: Diagnostics report from attempt_1490079327128_0048_r_000003_0: Container killed by the ApplicationMaster.
Container killed on request. Exit code is 143
Container exited with a non-zero exit code 143
I noticed it happens one large sorts but when i change the "Sort Allocation Memory" it does not help.
I tried changing other memory properties but yet, the solution eludes me. Is there a good explanation to how Mapreduce works and what's the interaction between the different components? What should I change? where do I locate the Java error leading to this?
