Cloudera Manager Installation failing

1
votes

I am trying to create a small cluster for testing purposes on EC2 using Cloudera Manager 5.

These are the directions I am following, http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM4Ent/4.7.1/Cloudera-Manager-Installation-Guide/cmig_install_on_EC2.html.

It is getting to the point where it executes, "Execute command SparkUploadJarServiceCommand on service spark" and it fails.

The error is "Upload Spark Jar failed on spark_master".

What is going wrong and how can I fix this?

Thanks for your help.

Can you show some logs? - Rico
I'm not sure where to find any additional information. That is all I am getting. The only change I have made to those directions is using the CM5 bin file instead of the CM4. - rdittmer
Apparently it was an open port problem. I opened up the ones Cloudera listed originally, but just opened up every single one and now it works. - rdittmer

Adding the findings as an answer.

You have to open all the required ports for your Cloudera Manager to install it's components correctly.

For a complete guide of ports you need to open refer to:

http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM4Ent/latest/Cloudera-Manager-Installation-Guide/cmig_ports_cdh4.html

If you are running Cloudera Manager in EC2 you can create a security group that allows all traffic/ports between the Cloudera Manager and its nodes.
