HDP Kerberos

hadoop.security.authentication=kerberos

alpine.principal=alpine/chorus.alpinenow.local@ALPINENOW.LOCAL
alpine.keytab=/home/chorus/alpine.keytab

mapreduce.jobhistory.principal=jhs/_HOST@ALPINENOW.LOCAL
yarn.resourcemanager.principal=rm/_HOST@ALPINENOW.LOCAL
dfs.namenode.kerberos.principal=nn/_HOST@ALPINENOW.LOCAL
dfs.datanode.kerberos.principal=dn/_HOST@ALPINENOW.LOCAL

CDH Kerberos

hadoop.rpc.protection=privacy (CDH only)
hadoop.security.authentication=kerberos
alpine.principal=alpine/chorus.alpinenow.local@ALPINENOW.LOCAL
alpine.keytab=/home/chorus/keytab/alpine.keytab
mapreduce.jobhistory.principal=mapred/_HOST@ALPINENOW.LOCAL
yarn.resourcemanager.principal=yarn/_HOST@ALPINENOW.LOCAL

Hive

hive.metastore.client.connect.retry.delay=1
hive.metastore.client.socket.timeout=600

Add this property if the value is different than 'Hive Metastore Location'
hive.hiveserver2.uris=jdbc:hive2://hdp23.alpinenow.local:10000/default

Hive Kerberos (add to Hive params)

hive.metastore.kerberos.principal=hive/_HOST@ALPINENOW.LOCAL

Add this property if the value is different than hive.metastore.kerberos.principal
hive.server2.authentication.kerberos.principal=hive/_HOST@ALPINENOW.LOCAL
