Cloudera manager fails to start trying to fetch parcels

[#1]

I am doing a manual install, I was able to add yum repo to install Cloudera Manager (CM), but when I try to start it, it show that it started successfully, but the logs show that it fails to fetch the Parcels from external repo. (logs below)

The nodes are on a VPC (in AWS) and yum is configured to use a proxy, but evidently the proxy setting in /etc/yum.conf is ignored. (which is understandable because that is probably used by yum command line and not the Java process.)

So here is my question, is there a way to instruct the CM Server to use a proxy to fetch the parcels? I tried setting HTTP_PROXY and HTTPS_PROXY env variable, but no luck. I am trying to avoid setting up a local repository.

Thank you and here is exception from logs: (this happens for all the parcels it tries to fetch, such as CDH, Kafka, Spark, etc... I only included the log for Sqoop)

[#2 · Accepted solution]

The issue is resolved. The exceptions were misleading; the real issue was this:

Exception in thread "MainThread" java.lang.IllegalArgumentException: Invalid value set for db.setupType, the valid values are EMBEDDED or EXTERNAL

I changed the default value for com.cloudera.cmf.db.sertupType in /etc/cloudera-scm-server/db.properties to EXTERNAL. It was set to INIT.
