[jira] [Commented] (HIVE-2776) Setting test.silent=false has not effect

    [ https://issues.apache.org/jira/browse/HIVE-2776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13286181#comment-13286181 ] 

Zhenxiao Luo commented on HIVE-2776:
------------------------------------

test.silent is set to be true by default, and there is no -nolog parameter passed to the hadoop command that submitted as a MapReduce Job.

When setting test.silent to be false, -nolog parameter is passed to the hadoop command, and configured the MapReduce Job.

This -nolog will only make effect when the MapReduce Job is failing. While, in most testcases, the MapReduce job succeeded, but the optimizer/compiler is doing wrong, so the result is different from the expected output.

My proposed solution:

1. Remove this "try "ant test ... -Dtest.silent=false" to get more logs." from QTestUtil, since this message does not make sense in the test context.
   Even if you set -Dtest.silent=false, you may get no detailed log(in most cases), since the MapReduce Job does not fail, the optimizer/compiler is doing things wrong.

2. Print these log info when a MapReduce Job is failing. while only happens in MapRedTask, should not be in MapRedLocalTask.

3. The property name is misleading, it seems like a test property, but actually, both MapRedTask and MapredLocalTask is using this property. We could either remove this property at all, and always print the log info when a MapReduce Job is failing as stated in #2, or choose another non-test related property name to determine the behavior of MapReduce Job failing logs.
