I am trying to install Cloudera Manager on AWS EC2 in Sydney Australia (availability zone: ap-southeast-2a) and get the following error (for both Express and Enterprise Data Hub):
Version: Cloudera Enterprise Data Hub Edition Trial 5.1.3 (#155 built by jenkins on 20140916-2347 git: b19677739ec4ef6c525684ea258763ba1b6333a9)
From what I can see in the source, ap-southeast-2 is not defined. Thanks for reporting this, I will file a bug report. Just to clarify, could you post your steps please?
Meanwhile, an alternative is to manually install Cloudera Manager on a single node, create more nodes for the workers and add them in CM manually. Does this help?
