             Summary: Stack advisor error for recommendations request
                 Key: AMBARI-14773
                 URL: https://issues.apache.org/jira/browse/AMBARI-14773
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 2.4.0
         Attachments: AMBARI-14773.patch

I installed cluster with 3 hosts and 4 services and on all services, except
HDFS (YARN, ZK, MR2) I get error on recommendation request for configs. You
are able to see it if you open browser console and open service configs page.

Request returns:

    
    
    {
      "status" : 500,
      "message" : "Stack Advisor reported an error: TypeError: 'NoneType' object is unsubscriptable\nStdOut file: /var/run/ambari-server/stack-recommendations/34/stackadvisor.out\n\nStdErr file: /var/run/ambari-server/stack-recommendations/34/stackadvisor.err"
    }
    

In stackadvisor.err file:

    
    
    Traceback (most recent call last):
      File "/var/lib/ambari-server/resources/scripts/stack_advisor.py", line 158, in <module>
        main(sys.argv)
      File "/var/lib/ambari-server/resources/scripts/stack_advisor.py", line 109, in main
        result = stackAdvisor.recommendConfigurations(services, hosts)
      File "/var/lib/ambari-server/resources/scripts/../stacks/stack_advisor.py", line 569, in recommendConfigurations
        calculation(configurations, clusterSummary, services, hosts)
      File "/var/lib/ambari-server/resources/scripts/./../stacks/HDP/2.3/services/stack_advisor.py", line 359, in recommendHDFSConfigurations
        super(HDP23StackAdvisor, self).recommendHDFSConfigurations(configurations, clusterData, services, hosts)
      File "/var/lib/ambari-server/resources/scripts/./../stacks/HDP/2.2/services/stack_advisor.py", line 104, in recommendHDFSConfigurations
        super(HDP22StackAdvisor, self).recommendHDFSConfigurations(configurations, clusterData, services, hosts)
      File "/var/lib/ambari-server/resources/scripts/./../stacks/HDP/2.0.6/services/stack_advisor.py", line 253, in recommendHDFSConfigurations
        dataDirs = hdfsSiteProperties['dfs.datanode.data.dir'].split(",")
    TypeError: 'NoneType' object is unsubscriptable
    

We are not sending dfs.datanode.data.dir if it is not HDFS service.
