Subject [jira] [Commented] (HIVE-17078) Add more logs to MapredLocalTask
Date Wed, 12 Jul 2017 23:15:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-17078?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16084891#comment-16084891

Yibing Shi commented on HIVE-17078:
-----------------------------------

I am trying to keep the current behaviour. With Hive CLI, by default Hive logs are not printed.
Some users may rely on the stdout/stderr information. I don't want to surprise them.
If you still think it is unnecessary to print child stdout/stderr to Hive stdout/stderr, I
can remove the corresponding code.

> By default, {{MapredLocalTask}} is executed in a child process of Hive, in case the local
task uses too much resources that may affect Hive. Currently, the stdout and stderr information
of the child process is printed in Hive's stdout/stderr log, which doesn't have a timestamp
information, and is separated from Hive service logs. This makes it hard to troubleshoot problems
in MapredLocalTasks.
