Hi @MSharma,

I wonder if you hit a temporary outage. I just tried and it seems that the servers are up and I can download the fiels. Can you try again now and let us know if you still have an issue?

Thanks!

Correct the network issue. Or use the following workaround: Create a temporary local repository as per the following KB article: [1] Deploying a Custom Patch Parcel Using Cloudera Manager https://cloudera-portal.force.com/articles/KB_Article/Deploying-a-Custom-Patch-Parcel-Using-Cloudera-Manager

Can you please let us know the OS and version and the contents of your /cloudera-manager repo file?

cat /etc/redhat-release

cat /etc/yum.repos.d/cloudera-manager.repo

Also, the full error if possible.

Thank you for the information. This does not appear to be the same issue as initiated in this thread.

However, the error is clear:

"ERROR Error, CM server guid updated, expected 93c963d9-3566-4f25-847a-faffb020866b, received ba4e4402-6ab3-4cdc-a403-39415df12824"

There is a 'cm_guid' file that is used by the Cloudera Manager (CM) server to know which host belong to it. It appears that this host may have been part of a different CM cluster or the database was recently changed. This keeps users from inadvertently pointing the agent ot another CM instance.

In any case, the solution is to:

1. Archive/remove the /var/lib/cloudera-scm-agent/cm_guid file.

2. Restart the agent:

sudo service cloudera-scm-agent restart

3. Run the Host inspector, from the Hosts page in CM and verisfy that all hosts are functioning. If other hosts fail, they too may be in this state.
