Rohini Palaniswamy commented on PIG-4897: ----------------------------------------- Makes sense. We can just go with the current patch which keeps things simple and clear. testScopeOfParamWithNestedRunCommand is in v04 patch but missing in v05 though. Can you also create a new jira for the macro case and update the comment for the testScopeOfParamWithMacro with that jira number. > Scope of param substitution for run/exec commands > ------------------------------------------------- > > Key: PIG-4897 > URL: https://issues.apache.org/jira/browse/PIG-4897 > Project: Pig > Issue Type: Bug > Reporter: Koji Noguchi > Assignee: Koji Noguchi > Attachments: pig-4897-v01-notestyet.patch, pig-4897-v02.patch, > pig-4897-v03.patch, pig-4897-v04.patch, pig-4897-v05.patch > > > 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.
