Hi @bhara,   You can check the Hue configuration from Hue UI to confirm if Hue is using Oracle database. Login as Hue admin user change the URL to https://<hue-host>:8888/hue/desktop/dump_config Then click desktop section Then search database from the page I attached a couple screenshots for above step 3 and 4. Step 3 screenshot: desktop section Step 4 screenshot: database configurations Thanks, Li ... View more

Hi @bhara ,   Both error messages points out you need to tune your Hue performance.   First thing you need to check if you are using the default SQLite DB. If so, you should move the database from the default database across to another database backend such as MySql/Postgres/Oracle, which handles locking better than the default SQLite DB. Hue should not be run on SQLite in an environment with more than 1 concurrent user. Here is the doc on how to switch the DB: https://docs.cloudera.com/documentation/enterprise/5/latest/topics/hue_dbs_0.html   You can also check this Hue performance tuning guide for more information on tuning Hue like load balancing etc: https://gethue.com/performance-tuning/   Thanks and hope this helps!
