So the following has to do with adding the HBase Thrift and Rest Server to
Ambari. Personally, I like using extensions because its isolates the
functions from the upgrade process. However, it doesn't look like an
extension can extend either a stack or a common-service.
Stacks => HDP 2.6, BigInsights 4.2.5
Goals:
Be able to add Thrift/Rest with configs
Add appropriate alerts
Recompile app.js to have them appear in the summary panel
QUESTION 1 => is it possible to extend this with an extension? Like Extend
HDP 2.3 instead of common-services?
QUESTION 2 => Is it possible to trigger a recompile of app.js with a flag?

First Try
Extension Pack
<metainfo>
<schemaVersion>2.0</schemaVersion>
<services>
<service>
<name>HBASE</name>
<extends>common-services/HBASE/0.96.0.2.0</extends>
#######thrift and rest components
</service>
</services>
</metainfo>
Result
Not able to add Thrift/Rest Server
Second Try:
Modifying HDP 2.3 Stack HBase metainfo.xml to add them:
Result:
able to add Thrift/Rest server with configs
add appropriate alerts
Only Rest shows up in the summary panel since REST came with BigInsights
4.0 (but was lost when it merged with HDP 2.3) after digging, this seems to
be because you need a stack change or extension to recompile app.js to
include the new information.
There also appears to be an inheritance problem when stacks operate on the
same common-service.
BigInsights 4.0 adds the HBase Rest Server, but this isn't anywhere in the
HDP Stack so it doesn't show up as a possibility. However, if you add a
reference to the HDP 2.3 metainfo.xml, it will pick up all of the
BigInsights code.
