ls: cannot access '/var/lib/ranger/yarn/': No such file or directory

found in yarn logs records like failed to save service-tags to cache file '/var/lib/ranger/yarn/policy-cache/yarn_cm_yarn_tag.json' java.io.FileNotFoundException: /var/lib/ranger/yarn/policy-cache/yarn_cm_yarn_tag.json (Permission denied) Could it be the core reason? How can i fix it?

Tried to run spark and zeppelin jobs. application placement rules are: -submitting user's name = <user> -place the application into queue named for user / set default queue to / use custom placement rules - tried to use static and dynamic queues The results are the same: application runs in default queue

Hello, trying to setup zeppelin + livy-on-spark3. Livy-on-spark2 is up and r spark3.sql runs fine, any spark3.pyspark code returns error "Interpreter died:". What could be wrong?

We've deleted credentials from AD and regenerated it, now zeppelin runs fine.

Nope. We can set queue for spark with --queue argument and it would work. But the rest requests are ignoring yarn placement rules.

Hello, sorry for a big delay. That solution didn't worked for me. I've set all parameters in Yarn and Hive-on-Tez, but test user going to default query anyway. Maybe I can check logs or something for that placement rules?

Hi, few hours ago zeppelin stopped to run queries and begins to throw errors like WARN org.apache.zeppelin.socket.NotebookServer: Job 20230217-161657_1725299508 is finished, status: ERROR, exception: null, result: %text javax.security.auth.login.LoginException: Unable to obtain password from user Its kerberized AD KDC cluster. ldapsearch and kinit with right principal works fine. /etc/hosts are fine too. The rest services on the cluster are green. http://hostname:port/api/credential/ returns {"status":"OK","body":{"userCredentials":{}}} What else can I check?

Hello, we run queries via zeppelin and livy.sql on CDP 7 If we run select everything is fine, but when we run create /drop table or insert - status became "error" but query is executing. What could be wrong?
