Hi @Mondi ,
Thanks for reaching out to Cloudera community.
The "com.mysql.cj.exceptions.InvalidConnectionAttributeException" in the log suggests that MySql JDBC driver version 8.x is being used. However, as pointed out by below doc, we recommend using only version 5.1 of the JDBC driver.
https://docs.cloudera.com/documentation/enterprise/6/latest/topics/cm_ig_mysql.html#cmig_topic_5_5_3
Please download the one from https://dev.mysql.com/downloads/connector/j/5.1.html and then install it in /usr/share/java. After that, retry the command.
Thanks and hope this helps!

Hi @ankesh_clo,
Could you please share outputs from below three commands on the host? This will help us to find out if there are any permissions issues etc.
ls -altr /var/lib/cloudera-scm-agent
and
ls -altr /opt/cloudera
and
ls -altr /opt/cloudera/parcels
Thanks,
Li

Hi @matagyula ,
Thanks for reaching out to Cloudera community.
Password complexity and account expiration for users in Cloudera Manager is available through external authentication backends. Please note, this need Cloudera Enterprise license.
You can configure external authentication to LDAP/Active Directory or SAML. Read more from below doc:
https://docs.cloudera.com/documentation/enterprise/latest/topics/cm_sg_external_auth.html
However, above does not apply to the CM internal users. We currently have an internal jira which will enhance the validation to the passwords for local CM users adhere to a reasonable policy and it will come in future releases.
Thanks and hope this helps!

Could you please share the Ambari server log ambari-server.log and see if we can find any error messages there? What database are you using for Ambari server?

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

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!

Hi @bhara ,
Thanks for reaching out to Cloudera community.
Hue cache some static files and that is very useful when talking to Hue API. Are you talking about the user does not need to re login Hue UI after you close the browser? Did the users log out the Hue application or did they just close the browser?
You may want to check this blog and see if the configuration "idle_session_timeout" helps:

Hi @Seeker90 ,
Thanks for reaching out to Cloudera community.
It looks like there is some missing permission and so could you please run the below commands as root user in hue node:
sudo -u solr solrctl sentry --list-roles
sudo -u solr solrctl sentry --list-privileges admin_role
and make sure you receive the below privileges when you run the below command:
[root@hue-test ~]# sudo -u solr solrctl sentry --list-privileges admin_role
Collection=*->action=*
Admin=*->action=*
Schema=*->action=*
Config=*->action=*
If you don't have the privileges, please use below command to add it:
sudo -u solr solrctl sentry --grant-privilege admin_role 'xxxx'
Hope this helps!
