Director 1.5 Unavailable Instances available at step at Requesting an Insance for Cloudera Manager

Roland — Fri, 16 Sep 2022 09:43:23 GMT

I am running Director version 1.5 on an Amazon instance that has both client and server on it.

When I run bootstrap-remote with my config file, a number of steps complete with messages.

It gets stuck right after it posts the essage 'requesting insance for CM'.

I can see the instances being built in AWS. The AWS completes checkout on the new machines and I can log into them.

However director waits on that step and eventually fails (see below).

Director screen output ----

The application.log has no messages that jump out as errors.

Any ideas where I should look?

If you look in the log, does it seem that Director is trying and failing to SSH into the newly provisioned instances? If so, you probably have a problem with your network or security group configuration. Can you SSH into one of the instances manually from the instance where you are running Director?

I found an application log that was in var/log/cloudera-director-server that had a lot more information. It confirms your suspicion.

It shows the servers be allocated and started:

Then I get a ton of these prior to it failing:

[2015-10-08 18:45:51] INFO WaitForSrverOnPortUntilTime/4 Attempting Connection to /10.0.0.[110,108, 112, 228, 111, 109]:22.

It just donned on my that in the security group I limited the port 22 access to my IP address. I am guessing that would prevent director from doing its work?

Is that a reasonable guess?

By "my IP address", I assume you mean your machine outside the cloud, rather than the AWS instance running Director. If so, then yes, that is almost certainly the problem. Director does its setup work on the Cloudera Manager and cluster instances via SSH, so you should ensure that your security groups allow that access.

jadair,

I made the change and I am well past that point (thanks!).

I am getting this error now. It references a log that appears to be an absolute address, but the directory doesn't exist.

This does not appear in the application.log, which appears to be relatively clean.

[ec2-user@ip-10-0-0-76 ~]$ Unexpected internal error (see logs): {"timestamp":1444337043467,"status":500,"error":"Internal Server Error","exception":"com.cloudera.launchpad.api.InternalProcessFailedException","message":"Server Error","path":"/api/v3/environments/Eastern-BD-Cluster%20Environment/deployments/Eastern-BD-Cluster%20Deployment/clusters"}

It appears after these messages:

Hmmm. That REST API call is meant to be listing the clusters under your "Eastern-BD-Cluster Deployment" deployment in your "Eastern-BD-Cluster Environment" environment. When you say that the log is clean, are you referring to the client log or server log? I am surprised to see a 500 error with no corresponding information in the server application log in var/log/cloudera-director-server.

I think I am going to restart the server and rerun. Perhaps there is something leftover form the earlier problems.

Jadair,

Thanks for your help. Although I had a few problems along the way - many of them reverted back to my need to fix my security group.

I appreciate our help.
