Hi @prakashpunj,   My research found this from other co-worker's notes: The error message seems related with mysql timezone and you can try to setup it using this doc: https://stackoverflow.com/questions/930900/how-do-i-set-the-time-zone-of-mysql   Could you please give it a try and let us know if that helps?   Thanks, Li ...

Hi @Dombai_Gabor,   From the error message, it looks like the Delegation tokens have expired. There is a possibility that HMS is using MemoryTokenStore.   Is this a test server? If so, please try below troubleshooting steps. 1. search below configuration from Cloudera Manager: Hive Metastore Delegation Token Store 2. Set the value to be: org.apache.hadoop.hive.thrift.DBTokenStore. 3. After the change, save and restart Hive and Hue Services. 4. See if the issue is resolved. This maybe related to the known bug https://issues.apache.org/jira/browse/HIVE-10574.   Hope this helps! ... View more

Hi @alcarin_ducil ,   Please take a look at this documentation: https://docs.cloudera.com/documentation/enterprise/latest/topics/cm_bdr_replication_source.html   Especially below notes: Cloudera recommends that TLS/SSL be used. A warning is shown if the URL scheme is http instead of https. After configuring both peers to use TLS/SSL, add the remote source Cloudera Manager TLS/SSL certificate to the local Cloudera Manager truststore, and vice versa.   Thanks and hope this helps. ...

Hi @HKG ,   We are sorry to hear you are having some trouble. Can you open a new thread and provide us with some background of what you are trying to do and what is happening. If you can give us some screen shots that would help make sure we understand what you are seeing.   Also, I noticed you mentioned you deleted db.properties instead of db.mgmt.properties which was mentioned in old threads. db.properties is the configuration file needed for Cloudera Manager database details. That file should not be deleted. Do you have a backup of the file? If so, please restore the file and set the permission to be: -rw------- 1 cloudera-scm cloudera-scm Then try to restart CM server again.   Hope this helps. If not, please open a new thread and provide more information.   Thanks! ... View more
