The below error appears after logging in the cloudera manager.

Following a restart of the cloudera manager service the error remains.

Has anyone got any helpful intel?

Resolved.

It was a buggy entry in the HOSTS table.

Just execute:

select *
from HOSTS
where ip_address is null or name is null;

Grab the host_id and update the record just in case removing it does any bad juju.

update HOSTS set name = 'ignoreme', ip_address = '0.0.0.0' where host_id = your_host_id_here;

Hello!

I'm relatively new to the Hadoop ecosystem. Can you tell me from where I would go about querying against the hosts table you mention? Is it a Zookeeper thing? Hive? Any advice or direction towards documentation is greatly appreciated. Thanks!

Found it myself, but in case someone else has the same question I did:

On a default CDH install, check /var/lib/cloudera-scm-server-db/data/generated-password.txt for the DB password. Then:

psql -h 127.0.0.1 -p 7432 -U cloudera-scm -W scm

HTH!

I am seeing an empty set of hosts

psql (8.4.20)
Type "help" for help.
