----------------------------------------

             Summary: Ambari is expecting hadoop client package and configuration, even if no HDFS components are installed on this host
                 Key: AMBARI-15627
                 URL: https://issues.apache.org/jira/browse/AMBARI-15627
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.2
            Reporter: Dmytro Grinenko
            Priority: Critical
             Fix For: 2.2.2


This happens during an ugprade from HDP 2.3.0 to 2.3.4.7. Couple nodes  have Kafka broker/Zookeeper installed with no clients or any other components. Hence, during the installation, there is no HDFS package installed on this node. However, during the start up Ambari expects this node to have /usr/hdp/current/hadoop-client/conf' during the start up:
