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

             Summary: Cannot deploy cluster without HDFS_CLIENT
                 Key: AMBARI-24681
                 URL: https://issues.apache.org/jira/browse/AMBARI-24681
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.7.0
            Reporter: Doroszlai, Attila
            Assignee: Doroszlai, Attila
             Fix For: 2.7.2


The attached blueprint cannot be deployed, because {{hadoop-env.sh}} is not saved by Ambari, because it requires {{HDFS_CLIENT}} component on at least one host:

https://github.com/apache/ambari/blob/8d145e0c04917866fd76690688826cf44065370e/ambari-server/src/main/resources/stack-hooks/before-ANY/scripts/hook.py#L32-L33

Datanode start fails with:

{noformat}
ExecutionFailed: Execution of 'ambari-sudo.sh su hdfs -l -s /bin/bash -c 'ulimit -c unlimited ;  /usr/hdp/3.0.0.0-1634/hadoop/bin/hdfs --config /usr/hdp/3.0.0.0-1634/hadoop/conf --daemon start datanode'' returned 1. ERROR: JAVA_HOME is not set and could not be found.
{noformat}

This appears in output from {{after-INSTALL}} hook:

{noformat}
Parameter hadoop_conf_dir is missing or directory does not exist. This is expected if this host does not have any Hadoop components.
{noformat}
