Andrzej Bialecki commented on PIG-21:
--------------------------------------
The problem with JobTracker URL can be solved by the following snippet:
if (ctx.getExecType() == ExecType.MAPREDUCE)
System.out.println("Job tracker: " +
JobTracker.getAddress(ctx.getConf()));
However, I'm not sure how to solve the other issues that you pointed out, I
still know too little about Pig internals ... There are no obvious places in
PigServer or PigContext that could provide this information - in case of (2) my
understanding is that the dependency order is determined just prior to store(),
using IntermedResult.compile(), so I don't think it's possible to show this
dependency order without specifying which alias we want to store.
In case of (3), I think this is a problem with IntermedResult.lp.getSchema(),
which retains the original alias that it was assigned to (or maybe I'm totally
confused ...).
So, for now I'm not able to fix these issues.

> After a long interactive session with grunt I lost track of what kind of
> queries I defined, and then re-defined. It would be nice to have the ability
> to show all defined aliases, and other context variables, such as the
> filesystem, jobTracker, user jars and Configuration.
