@Geoffrey Shelton Okot You can follow instructions similar to this: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.2/bk_Security_Guide/content/_set_up_truststore_for_ambari_server.html. Basically you'll need to import certificates to your truststore/keystore.

@cmcbugg You can use the following jvm options to add additional logging for Kerberos: -Dsun.security.krb5.debug=true -Dsun.security.jgss.debug=true -Djavax.net.debug=all When you run your kafka process at DEBUG log level, it should ideally log the kerberos ticket exchange, which will contain the KDC coordinates. Hope this helps

@Morten R. What do you see in HS2 logs and also the application logs? Can you change the log level to DEBUG and then try to get the error stacktrace?

Hi @Davide Vergari, If you ask beeline to run commands in one file, they will run sequentially. However, you could try the following: 1. Split the queries in different files and run multiple beeline commands in different threads in your program. 2. Use JDBC where you can open multiple connections in different threads and run queries on each connection. Hope that helps.

@jzhang The _HOST in the principal name gets replaced by the fully qualified domain name of the host at runtime. However, this needs the reverse DNS to be configured correctly on the box. Could you check that?

It would be good to look at the app logs for the query to see where the tasks are stuck. Some helpful tips to debug tez: https://cwiki.apache.org/confluence/display/TEZ/How+to+Diagnose+Tez+App

HiveServer2 and Metastore servers can be on different machines. HS2 can also be configured to get metadata via a remote Metastore server (HS2 opens a TCP client connection to Metastore server) or use an embedded Metastore server (in which case HS2 calls the Metastore Server's API directly: use hive.metastore.uris="" in hiveserver2-site.xml to achieve that).

@Christian Guegi Do you see this issue only when running multiple worflows in parallel?
