Sumit Mohanty commented on SLIDER-763:
--------------------------------------
"client install" is preferable considering both "install-package" and
"install-keytab" have their twins in "package install" and "keytab install". I
was thinking if we should get one step further - "execute --component A_CLIENT
--command INSTALL". This is motivated by the question - should client install
be a set of steps implemented by the Slider CLI or should it be invoking a
script in the package through the agent code. The later is more flexible and
in-line with all other commands. The former will be simpler but will also limit
how a client wrapper is installed or configured.
The "execute" option also allows us to issue "execute --component HBASE_MASTER
--command START --template appConfig.json" on local disks to simulate START
command. This will be only for debugging as the purpose is to lay out the files
and then invoke the scripts. It makes it easier to debug as you do not need to
deploy through YARN. Also, once the files are in place (simulated container
file layout) app developers can edit the config and call the command again to
debug the scripts.
However, for 0.80, it may be better to take it one step at a time. Implement
"client install" that in-turn calls "execute --component THE_CLIENT --command
INSTALL" so that we have the plumbing for general purpose calls that can be
extended in future for local debugging.

>
> It should be possible to mimic the agent's environment and run the INSTALL
> command locally for a component to obtain a client installation of an
> existing app. It may require the app to have a CLIENT category of component.
> If we had this, each app would no longer need a special script for doing
> client setup.
