This WARN logs should not cause any issue,


1) however if you want to remove this configs, you can use below syntax to delete the config on specific component config_type(Configs can be searched in ambari -> hive configs filter box to know which file to be updated)

/var/lib/ambari-server/resources/scripts/configs.py -u <<username>> -p <<password>> -n <<clustername>> -l <<ambari-server-host>> -t <<ambari-server-port>> -a <<action>> -c <<config_type>> -k <<config-key>>

eg.,

/var/lib/ambari-server/resources/scripts/configs.py -u admin -p <<dummy>> -n cluster1 -l ambari-server-host -t 8080 -a delete -c hive-site -k hive.mapred.strict

/var/lib/ambari-server/resources/scripts/configs.py -u admin -p <<dummy>> -n cluster1 -l ambari-server-host -t 8080 -a delete -c hive-site -k hive.mapred.supports.subdirectories

This is the reference for configs.py https://cwiki.apache.org/confluence/display/AMBARI/Modify+configurations#Modifyconfigurations-Editco...


2) To remove log4j warning, goto ambari -> hive configs -> advance hive-log4j, comment below line

log4j.appender.DRFA.MaxFileSize


After the above 2 changes, restart hive services, all those 3 warns should go away.
