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

             Summary: ATS needs a dynamic dependency on Tez and Spark
                 Key: AMBARI-17111
                 URL: https://issues.apache.org/jira/browse/AMBARI-17111
             Project: Ambari
          Issue Type: Bug
          Components: stacks
    Affects Versions: 2.2.0
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
            Priority: Blocker
             Fix For: 2.4.0


Today, ATS can be installed without Tez, which is fine.
However, when you add Tez, the client also needs to be installed on the host that has ATS.
Without it, the Tez View will not work and be unable to display detailed information.
A similar problem exists for Spark, in which YARN shouldn't require Spark, but installing Spark should require reconfiguring YARN and installing Spark client on the ATS box.
This has existed from the time that Spark was added in Ambari 2.2.
STR:
Install a 3 node cluster with HDP 2.3 or higher.
Install ATS on host 1
After installation, add Tez service, and only install the Tez client on host 3
The ATS host should also install Tez client.
