Artem Ervits commented on OOZIE-3026:
-------------------------------------
[~andras.piros] there is an entry for openjpa in oozie-log4j.properties
https://github.com/apache/oozie/blob/master/core/src/main/conf/oozie-log4j.properties#L99
it doesn't take effect, I tried
https://github.com/apache/oozie/blob/master/core/src/main/resources/oozie-log4j.properties
as well. From my understanding, this only takes effect via persistence.xml
during openjpa-maven-plugin enhance stage and thus during build only
http://openjpa.apache.org/enhancement-with-maven.html and
http://people.apache.org/~mikedd/openjpa/openjpa-maven-plugin/enhance-mojo.html
so I am not sure if enabling that via oozie-log4j.properties is necessary?
