Hi All,

Will clarify the WORKARROUND in case it helps anyone...

The wizard installer is composed of 2 phases defined in the "Select Repository" screen:

[Phase1] The Cloudera Manager processes (jdk if needed, cloudera-scm-agent, cloudera daemons)

[Phase2] The Runtime (the roles like impala, kudu, Hive...)

Main issue was that the install attempt for the Phase1 did not took into accout the Poxy added for the Runtime repo, failing all the time, even setting the proxy in /etc/bashrc for letting eny user to use it.

Here are two solutions:

1º to manuall install the services required by the [Phase1] using the /etc/yum.repos.d/cloudera-manager.repo (used yum in my case)

openjdk8-1.8.0_372_cloudera-1.x86_64, cloudera-manager-agent.x86_64 in all servers. then retry the wizard (it will detect the packages are already installed and jump to the Runtime part)

2º setting the proxy in /etc/yum.conf

proxy=http://user:pass@proxy-IP:8080

and disable all other repos (I had to do this to avoid yum to fail) NOTE: maybe the installer fails because the Cloudera-manager-agent.x86_64 has many dependencies and some of then might be in the OS repo (This is why I installed it manually)
