Subject [jira] [Commented] (HIVE-13086) LLAP: Programmatically initialize log4j2 to print out the properties location
Date Thu, 18 Feb 2016 21:48:18 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13086?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15153179#comment-15153179

Prasanth Jayachandran commented on HIVE-13086:
----------------------------------------------

This is not related to SLF4J's runtime binding. This is just to avoid erroneous autoconfiguration
of logging for llap. [~gopalv]'s comment https://issues.apache.org/jira/browse/HIVE-13027?focusedCommentId=15150141&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15150141

suspects logging initialized from some other properties files. If for some reason logging
is initialized with wrong properties file this initialization (reconfiguration) will make
sure llap always uses llap-daemon-log4j2.properties file. Also it prints which file it picked
up from classpath.

> In some cases, llap daemon gets initialized with different log4j2.properties than the
expected llap-daemon-log4j2.properties. It will be easier if programmatically configure log4j2
so that we can print out the location of properties file that is used for initialization.
