> 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.
