HIVE-3978 changed the seperator for HIVE_AUX_JARS_PATH to : from ,. However, it's expected that it's , later on in the script, specifically here:
AUX_PARAM=`echo $AUX_PARAM | sed 's/,/,file:\/\//g'
HIVE_AUX_JARS_PATH should have : instead of , as separator since it gets appended to HADOOP_CLASSPATH
Hive command line option --auxpath still does not work post HIVE-5363
Hive --auxpath option can't handle multiple colon separated values
