----------------------------------------
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:
