Beeline with Kerberos and ServiceDiscoreryMode not working

[#1]

Error:

Error: Could not open client transport for any of the Server URI's in ZooKeeper: Unable to read HiveServer2 configs from ZooKeeper (state=08S01,code=0)

Issue: Beeline connection failing using Kerberos principal and ServiceDiscoveryMode

beeline -u "jdbc:hive2://zk1.com:2181,zk2.com:2181,zk3.com:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2;auth=KERBEROS;principal=myuser/hiverserver2@EXAMPLE.COM;httpPath=cliservice;saslQop=auth-conf"

Resolution: We do not need to pass the kerberos principal within the beeline command because we are using zookeeper. You must already have valid Kerberos ticket.

Example:

kinit myuser

beeline -u "jdbc:hive2://zk1.com:2181,zk2.com:2181,zk3.com:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2;transportMode=binary;httpPath=cliservice;saslQop=auth-conf"

Note: You must have a valid ticket first. If no valid ticket is present you will see an error like the following:

The error in the log "echanism level: Failed to find any Kerberos tgt"
