Loggers in Trafodion Java classes
Hi,
I'm looking at HBaseClient.java, and I would like to use the logger there.
Can someone remind me how to turn on the logging?
Also, where will the log file go? (If the answer is different on a workstation than it is on a cluster, please answer for each.)
I'll add this info to the wiki Debugging Tips page.
Thanks,
Dave

Hi,
Thanks Selva and Sean. I've updated https://cwiki.apache.org/confluence/display/TRAFODION/Debugging+Tips with these tips. Feel free to comment and/or update.

Also, from the top of the source file you can see the file is part of package org.trafodion.sql; So in the file Selva mentions you should put a line like log4j.logger.org.trafodion.sql=<desired logging level>
Thanks,
Sean

Logger configuration is at $TRAF_HOME/conf/log4j.hdfs.config The log file is written to $TRAF_HOME/logs/trafodion.hdfs.log
It is same for workstation and the cluster. In case of cluster, you need to set it up in every node.
