Issues on CDH 5.8.0

Contributor

Hi,

 

We are facing two issues as per below;

 

1] 

We have setup cloudera manager(5.8.1)  and CDH (5.8.0) using Installation Path A method. However, we have used custom postgres[9.4] database instead of Embedded Database. We were required to provide username,database and password for oozie,hue,hive and Report manager while setup.

 

Except, Report manager all other connection succeded. For report manager having username/database as 'rman' it was giving an error as "Logon denied for user/password. Able to find the database server and database, but logon request was rejected." Although, we are able to connect to the same custom db from terminal with same credentials. When we changed the username/database otherthan rman e.g. rman2[we created this db] the testconnection succeded.

But, now in cloudera manager service, we are getting Process Status error for report manager, which is giving an error in log as 

"com.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@71c0aadc -- Acquisition Attempt Failed!!! Clearing pending acquires. While trying to acquire a needed new resource, we failed to succeed more than the maximum number of allowed acquisition attempts (5). Last acquisition attempt exception:
org.postgresql.util.PSQLException: FATAL: password authentication failed for user "rman2"

 

2] When we downloaded,distributed and activated kudu parcels, latest or kudu 0.9.0 from cloudera manager and tried to add it from 'add a service' option, it did not shows us Kudu service option.

 

Can you please help us on the same. Really appriciate any help on the same.

 

Thanks,

Amit

Hi Team Cloudera,

 

In above case Issue #2 resolved. However, In case of, Issue #1 we have observed that while installation although we have selected custom Database and provided the custom database details[postgresql] on instllation page, the cloudera is using the default embedded database for oozie,hue,hive and report manager, as we were able to fix this issue #1 when we provided the credentials from db.mgmt.properties which was having embedded DB credentials and we found that the oozie,hue,hive and report manager DBs are created into embedded DB.

 

This is not expected since we have provided the custom database details and it seems that cloudera manager is not using the provided custom database details.

 

Can you please help us on the same, as this is not only an installation issue but this is also puzzling what we can do in case of, back up of cloudera manager.

 

Thank you,

Amit

Super Guru

If you want control over your databases, Use Path B instead.  Path A is for testing and installes/configures with the embedded db.

 

http://www.cloudera.com/documentation/enterprise/5-8-x/topics/cm_ig_install_path_b.html#cmig_topic_6...

 

Path A is intended for installations that will leverage the embedded db.

 

Cloudera Manager's database configuration is stored in /etc/cloudera-scm-server/db.properties

If you are using the embedded database, then db.mgmt.properties will be created automatically in /etc/cloudera-scm-server

 

Regards,
