Creating a cluster, i get Failed as status and the error message tells me to contact Cloduera.

 

Is there a way to troubleshoot using the logs on s3?

 

All machines are spun up and running, even cloudera manager is accessible but the cluster status is failed.

Hi @uzubair,

 

Just touching base to see if you were able to resolve this issue, and if not, were you able to create a support case through through the Altus Web UI (Altus Web UI -> Support -> Support Center -> Technical Support;  Component = Altus Data Engineering;  Sub-Component = Clusters)?

 

Thanks,

Hi @uzubair,

 

Thanks for raising this to our attention.

 

You may be able to check the S3 bucket (if configured) for log output that may help with determining why the described symptoms occurred. 

 

Given the nature of this issue, are you able to create a support case through the Altus Web UI (Altus Web UI -> Support -> Support Center -> Technical Support;  Component = Altus Data Engineering;  Sub-Component = Clusters)?

 

Would you be able to provide some additional details within the support case as well, in particular:

 

  1. The output of the following command as well (if you have the Altus CLI installed):
    $ altus dataeng describe-clusters --cluster-name <cluster_name>
  2. Cluster Creation time
  3. # of Workers and Computer workers created,  and if spot instances were used
  4. Was there an Instance Bootstrap Script used?  If so can you attach that to the Support Case as well?
  5. Has any other Cluster creations failed in this same manner recently, or has this only been a single manifestation?

 

Kind Regards,

 

Anthony

I was able to resolve the issue...was able to run Spark jobs in Altus using Talend Big Data.

The issue had to do with the VPC setup in my Amazon environment. It wasn't setup properly. I picked a different region where the VPC is setup correctly and I was able to launch the cluster.

@uzubair,

 

Great to hear!  Thanks for getting back and letting us know.

One typo correction to Anthony's reply above, the CLI command to retrieve information about a cluster is as 'describe-cluster' and not 'describe-clusters'.
