Could not start cloudera-scm-server after upgrading Cloudera Manager 4 to Cloudera Manager 5

Hi,

 

After successful upgrading I tried to start cloudera-scm-server service but failed. There was a bunch of errors in cloudera-scm-server.log

it was trying to download the manifest from http://archive.cloudera.com/sqoop-connectors/parcels/manifest.json

However, it is actually located there http://archive.cloudera.com/sqoop-connectors/parcels/latest/manifest.json.

 

Could you, please, advise me if there is any way to fix it?

 

Thanks

Re: Could not start cloudera-scm-server after upgrading Cloudera Manager 4 to Cloudera Manager 5

Hi,

This is a pretty strange situation. It seems like somehow you have an empty string in the COMMANDS table, column ARGUMENTS. From what we can tell in the code, this should be totally impossible, since we always reject attempts to set this to an empty string (Null is ok).

Was this table manually modified?

What kind of database are you using?

To fix the problem, the following should work:
1) stop CM (sudo service cloudera-scm-server stop)
2) back up your database (just in case!)
3) log in to the database (see db host / port / database name / username / password in /etc/cloudera-scm-server/db.properties)
4) Run the following query:
update PROCESSES set ARGUMENTS=NULL where ARGUMENTS='';
(note that '' is two single quote characters, not a double-quote character)
5) start CM (sudo service cloudera-scm-server start)

Thanks,
Darren

Re: Could not start cloudera-scm-server after upgrading Cloudera Manager 4 to Cloudera Manager 5

Hi Darren,

 

Thanks a lot for your reply.
Your fix with updating COMMANDS table helped. The upgrading completed successfully.
We are using Oracle now. Have migrated from Postgres to Oracle recently. It might cause this kind of discrepancies.

 

I really appreciate your help.

 

Thanks,
Eugene

Re: Could not start cloudera-scm-server after upgrading Cloudera Manager 4 to Cloudera Manager 5

Hi Eugene,

Glad you got it working!

That probably explains it. Oracle has special handling for empty string vs null, and it probably did something weird in your migration scripts.

Thanks,
Darren
