Dawson Choong commented on BIGTOP-1222:
---------------------------------------
The patch looks promising so far. However, if I run "gradle clean compileGroovy
test" in the bigtop/bigtop-smoke-tests directory, I am getting an exception
"undeclared env variable: PIG_HOME," despite the fact that I may not want to
test pig. It would be nice if the user could write which tests they want to run
on the command line (ex: $ gradle hadoop cnode) and gradle will do the rest of
the work as opposed to manually selecting tests in build.gradle. Does this seem
feasible? I would be happy to work on this with you [~jayunit100]

> (Rewritten the description for clarity)
> We need an easier way to run bigtop smoke tests, and gradle provides this:
> 1) Easy to script/modify
> 2) Human readable
> 3) equally oriented towards both groovy and plain old java
> The advantage of this method to running smokes :
> 1) No need to compile a jar : this is a costly step and not much value added,
> also creates indirection which can make debugging a broken test very hard.
> 2) Simple: A smoke test doesnt need to make low level API calls or be
> compiled against the right APIs - rather, it should test the end user
> interface ("hive -q ....", "pig -x ....", "hadoop jar ....", and so on).
> 3) Customizable: The smoke tests shouldnt require users to have to write XML
> and debug environmental variables / grep around for System properties etc.
> Rather, a high level controller should do all that checking for you.
> The initial idea was to write a python/bash implementation wrapper of
> scripts, but that was replaced by the idea of using gradle. The advantage of
> gradle is that we don't need to manually set the classpath and run groovy
> commands: Gradle wraps groovy scripts in their native java context quite
> nicely - but it doesnt add any other unnecessary overhead (xml, jar files, no
> need for complex xml tag wrappers for simple tasks - just plain groovy code).
> So, here the goal is just to create a nice, clean, extensible non-jar,
> non-API dependent gradle runner for the smoke tests which exersizes the
> hadoop cluster the same way a typical end-user would.
