Alejandro Fernandez updated AMBARI-20322:
-----------------------------------------
    Description: 
HDP 3.0 support for Slider with configs, kerberos, widgets, metrics, quicklinks, and themes
Flatten from HDP 2.0.6 - 2.6 into common-services, and reference in HDP 3.0

In HDP 3.0, we have created a new stack definition that does not inherit from other stacks,
in order to reduce the complexity of having to analyze older stacks.
This means that we need to create a service definition (metainfo.xml, configs, kerberos, widgets,
metrics, quicklinks, and themes) that is equivalent to what is inherit and deleted from all
of the previous stacks.
A merge needs to account for additions, overrides, and deletions.
metainfo.xml and configs perform a merge of older versions
kerberos.json always seems to override the previous file

Because the bits for this service may not yet be available in the HDP 3.0 repo, 
the task is to ensure that /api/v1/stacks/HDP/versions/2.6/services/SLIDER (which uses inheritance)
is equivalent to the flattening of /api/v1/stacks/HDP/versions/3.0/services/SLIDER .
Please take a look at how this was done for ZK, HDFS, and YARN/MR.

This means that you will not be able to actually install the service for now, but can still
perform validation during the Install Wizard that the correct components and configs show
up.

Slider is being added to the HDP 3.0 stack temporarily in order to unblock Hive LLAP. Later
in the HDP 3.0 release, Slider RPM will be part of YARN. We may still keep Slider as a Service,
but it may move as a component of YARN instead.

Slider version in common services is 0.91.0

  was:
Create a Service Advisor script for Slider in HDP 3.0 Tech Preview.
The Service Advisor must encapsulate all of the logic inherited/overwritten from HDP 2.0.6
through HDP 2.6
