Subject Logging configuration
Date Wed, 09 Sep 2015 00:37:12 GMT
We are having an issue for which we would like to enable logging.  The
component is
org.apache.hadoop.hive.ql.exec.persistence.HybridHashTableContainer.  We
have added entries to both hive-log4.properties
and hive-exec-log4j.properties as follows:

log4j.appender.ts=org.apache.log4j.FileAppender
log4j.appender.ts.file=/tmp/myhive.txt
log4j.appender.ts.layout = org.apache.log4j.SimpleLayout
log4j.logger.org.apache.hadoop.hive=INFO,ts

We see the component mentioned above in the stack trace for the exception
we are troubleshooting.  However, we see nothing in either the hive log or
our custom log appender.

We have tried naming the entire component, changing INFO to DEBUG, etc. but
no output for the LOG.info() line we see in the source code for the
component (which is in the method that is part of the stack trace).  We do
see other INFO type messages in the log that we don't normally see.  We did
restart hiveserver2 prior to running the problematic query.

How do you configure logging for a single component, or even package tree
like org.apache.hadoop.hive
