I have resolved this, so I ll share what the issue was,
I had set HIVE_AUX_JARS_PATH in my hive-env.sh
as
HIVE_AUX_JARS_PATH=$HIVE_AUX_JARS_PATH,$HIVE_HOME/lib/jar1.jar,$HIVE_HOME/lib/jar2.jar,$HIVE_HOME/lib/jar3.jar.
The empty HIVE_AUX_JARS_PATH was causing the exception.
The following fix made it work
if [ -z "$HIVE_AUX_JARS_PATH" ]; then
HIVE_AUX_JARS_PATH=$HIVE_HOME/lib/jar1.jar,$HIVE_HOME/lib/jar2.jar,$HIVE_HOME/lib/jar3.jar
else
HIVE_AUX_JARS_PATH=$HIVE_AUX_JARS_PATH,$HIVE_HOME/lib/jar1.jar,$HIVE_HOME/lib/jar2.jar,$HIVE_HOME/lib/jar3.jar
Thanks,
Sam
