Is your cluster kerberized? Log says "Caused by: org.apache.hadoop.security.authentication.client.AuthenticationException: Authentication failed, status: 403, message: Forbidden" Can you check if you are running the job with user having valid kerberos ticket?

Are all queries failing via java api or just this one? Can you post complete error stack? I see hive "doHiveTableCreation" method, did table get created successfully?

1) Login to Ambari -> Hive -> Config. Check the mysql connection properties to determine which mysql server is currently configured to use. 2) Verify hive works and you are able to access metadata. 3) If you are able to access metadata, go to ambari -> hosts -> select host hosting 2nd instance of mysql. 4) the services is probably stopped or in installed failed state. click on actions and look for delete option.

If the server was erased an rebuilt with same IP and Hostname, you may have to do these steps - 1) Stop ambari agent form the rebuilt host. 2) Use Ambari rest API to delete each services that ambari thinks this host has/had 3) Delete the host from Ambari 4) Restart ambari server 5) Add as a new host.

Hi, How does Ambari create keytabs and principals when AD KDC is being used since kadmin command does not work? is it programatically or through a script similar to kerberos_setup.py in ambari resources directory?

Do you see anything in log files of Hive/Tez? Go to Hive shell. Create test table and load some data to that table. See if Tez is invoked and query runs fine. post the hive log console and Hive log file errors if it fails.

To troubleshoot 1) Kill all existing running/waiting applications. On terminal type "Yarn application -list". From the list, for each application id listed do "yarn application -kill <applicationid>". 2) Go to Ambari UI and select mapreduce. on top right, service-> run service check. Ambari will automatically run test mapreduce job. if that fails post the log here. 3) Do the same for Hive service and Yarn service one service check at a time.
