Prasanth Jayachandran updated HIVE-11572:
-----------------------------------------
Description:
As part of HIVE-11304, we moved from Log4j1.x to Log4j2. But DataNucleus log
messages gets logged to console when launching the hive cli. The reason is
DataNucleus is trying to load Log4j1.x Logger by traversing its class loader.
Although we use log4j-1.2-api bridge we are loading log4j-1.2.16 jar that was
pulled by ZooKeeper. We should make sure that there is nog log4j-1.2.16 in
datanucleus classloader hierarchy.
DataNucleus logger has this
{code}
NucleusLogger.class.getClassLoader().loadClass("org.apache.log4j.Logger");
loggerClass = org.datanucleus.util.Log4JLogger.class;
{code}
