Cloudera manager server shutdown few seconds after starting

Created ‎01-09-2018 07:04 AM

Hello all,

 

We're trying to install Cloudera Enterprise (none-production, just for POC purpose ) , and we had to go with Path C as we aren't allowed to connect to the Internet .

 

We followed steps as described in the documentation (tarball) :

https://www.cloudera.com/documentation/enterprise/latest/topics/cm_ig_install_path_c.html#cmig_topic...

 

 

We went with creating externla datastore for Cloudera manager server as described here (Preparing a Cloudera Manager Server External Database - PostgreSQL ) :

https://www.cloudera.com/documentation/enterprise/latest/topics/cm_ig_installing_configuring_dbs.htm...

 

All steps were successful and we verified that all databases were created and we were able to login

 

 

We were able to start the clouder manager agent with no issues.

 

However, when we start clouder manager server we always get :

[xxx@dyyyyyyy init.d]$ sudo ./cloudera-scm-server start
[sudo] password for xxx:
Starting cloudera-scm-server: [ OK ]
[xxx@dyyyyyyy init.d]$ sudo ./cloudera-scm-server status
cloudera-scm-server (pid 3779) is running...
[xxx@dyyyyyyy init.d]$ sudo ./cloudera-scm-server status
cloudera-scm-server (pid 3779) is running...
[xxx@dyyyyyyy init.d]$ sudo ./cloudera-scm-server status
cloudera-scm-server (pid 3779) is running...
[xxx@dyyyyyyy init.d]$ sudo ./cloudera-scm-server status
cloudera-scm-server (pid 3779) is running...
[xxx@dyyyyyyy init.d]$ sudo ./cloudera-scm-server status
cloudera-scm-server (pid 3779) is running...
[xxx@dyyyyyyy init.d]$ sudo ./cloudera-scm-server status
cloudera-scm-server dead but pid file exists

 


when we check the log :

@Matar,

 

From the looks of things, Cloudera Manager cannot connect to the database so it cannot start.

You shared some of the stack traces, but I trust there was more information in further stacks that might show the underlying connection problem at the JDBC driver level.

 

Aside from the suggestions made by @csguna, you might try connecting with psql using the same connection information you have in the db.properties file to confirm that you can see the database with the psql client.

@bgooley thank you so much ..

You shared some of the stack traces, but I trust there was more information in further stacks that might show the underlying connection problem at the JDBC driver level. --> how can I get more details ?

 

Aside from the suggestions made by @csguna, you might try connecting with psql using the same connection information you have in the db.properties file to confirm that you can see the database with the psql client. --> I've already done that and I was able to connect without any issues

@Matar,

 

I believe you may be hitting an issue with a mixture of the Postgres driver that CM ships with (it is an old 9.0 driver) and the Postgres server verison you are using.  You may need to update the CM driver.

At this time, we have adjusted the way that you can configure the postgres driver in CM, but that will not be included until a future release.

 

For now, I believe you can try putting an updated driver that aligns with your postgres server in /usr/share/java.

 

Make sure, though, that there are no other postgres drivers already in that directory.  I am pretty sure that the new driver will be picked up that way.

 

After that, give starting CM a try.

@Matar,

 

I reread my post and it may be confusing; I will try to clarify.

The exceptions you are seeing match some problems we had in internal Cloudera testing regarding Postgres 10.

Until a version of Cloudera Manager ships with a later driver, the driver that Cloudera Manager uses by default is not compatible with the Postgres 10.

 

After taking a closer look at the code, I believe you may need to do the following:

 

- cd to /usr/share/cmf/common_jars

- backup postgresql-9.0-801.jdbc4.jar to another location... it is not really necessary, but just to be safe...

- delete /usr/share/cmf/common_jars/postgresql-9.0-801.jdbc4.jar

- delete the link: /usr/share/cmf/lib/postgresql-9.0-801.jdbc4.jar

- Add your update postgres driver in /usr/share/cmf/common_jars/

- Create a link to it in /usr/share/cmf/lib

- Try starting Cloudera Manager.

 

I hope this helps!

Thanks if you can try it out.

 

-Ben
