             Summary: The Cluster Install Wizard fails on task DRPC Server Install
                 Key: AMBARI-25255
                 URL: https://issues.apache.org/jira/browse/AMBARI-25255
             Project: Ambari
          Issue Type: Bug
          Components: ambari-agent
    Affects Versions: 2.7.3
         Environment: CentOS 7.6

Ambari 2.7.3

HDP 3.1.0

Install on single-server as Non-Root
            Reporter: Opher Shachar


Installing HDF 3.4.0. The documentation starts me up with Ambari 2.7.3 that goes on to install HDP 3.1.0.

I'm installing on a single server as Non-Root following the documentation [here|https://docs.hortonworks.com/HDPDocuments/HDP3/HDP-3.1.0/securing-credentials/content/ambari_sec_how_to_configure_ambari_server_for_non_root.html] and [here|https://docs.hortonworks.com/HDPDocuments/HDP3/HDP-3.1.0/securing-credentials/content/ambari_sec_how_to_configure_an_ambari_agent_for_non_root.html].

When installation starts (after pressing Deploy) I get a failure during "DRPC Server Install"

{noformat}
The workaround is to do the following:
{code:sh}
cd /usr/hdp/current
rm -rf storm-client
ln -s /usr/hdp/3.1.0.0-78/storm storm-client
{code}
and retry.
