Rohini Palaniswamy commented on PIG-4897:
-----------------------------------------
Few minor comments
- We would always want to deleteOnExit. So not sure if that needs to be a
method argument
- Can we have one testcase with run -param output=xxx which will override
the %default output value in the script?
> Scope of param substitution for run/exec commands

> Project: Pig
> Issue Type: Bug
> Reporter: Koji Noguchi

>
> After PIG-3359, pig param substitution became global in that parameter
> declared in the pig script called from {{run}} or {{exec}} would live after
> that script finishes.
> This created an interesting situation.
> {code:title=test1.pig}
> exec -param output=/tmp/deleteme111 test1_1.pig
> exec -param output=/tmp/deleteme222 test1_1.pig
> {code}
> {code:title=test1_1.pig}
> %default myout '$output.out';
> A = load 'input.txt' as (a0:int);
> store A into '$myout';
> {code}
> Running {{test1.pig}} would try to run two jobs that both tries to write to
> /tmp/deleteme111 and fail. (Second param output=/tmp/deleteme222 is ignored.)
