Hi, I am evaluating DSS, so I installed it in my server and added a 2 weeks enterprise trial license.

I am facing a Cloudera CDH 5.12 cluster, kerberized.

I am able to connect and browse HDFS, but Hive connection is not working.

This is the error in log file backlog.log

    ... 68 more

Of course I tried to impersonate the user on the machine via kinit and open a beeline session, with success. For this, I copy-pasted the connection string in the log file, and if I add double quotes in the connection string, it works. Without it doesn't (which is correct).

For the record, this command issued from dataiku's node CLI succedes:


beeline -u "jdbc:hive2://cdhmaster02.my.corp:10000/default;principal=hive/cdhmaster02.my.corp@MY.CORP"

What do I need to check ??

Thanks

Bill

    Hi,

    It looks like you have added a "Connection property" in the Hive connection settings (in Administration > Settings > Hadoop) but didn't fill anything in the key. You will need to either make sure the property is filled or remove it.
