Hi everyone,   I successfully set a Virtual Private Cloud on AWS and started an instance using the Cloudera Director AMI (ID ami-2957655e, created on October 16).   I logged into its Web panel, added an environment, and then attempted to add Cloudera Manager. I did not attempt to go as far as adding a cluster too, because I keep getting a bootstrap_failed error. This has happened a couple of times already, with the same error.   (OS: the tmplate for Manager and cluster instances uses an Amazon provisioned AMI running CentOS 6.5. The template uses t2.micro instances. Very small, I know, but this is excludsively to learn the workflow and how to use the interface. Once I see everything running smoothly, I will switch to larger sizes. What follows doesn't seem to be a memory issue anyway.)   I checked the /var/log/cloudera-director-server/application.log and I can see that the Director can SSH into the other instance, but then it throws this exception, something to do with Google's Guava library:   [2015-10-24 00:17:19] ERROR [pipeline-thread-1] -
