Cheolsoo Park updated PIG-3169:
-------------------------------
Attachment: PIG-3169-hotfix.patch
The issue is that the test cases generate input files under /tmp and use them
across MR jobs:
{code}
pig.registerQuery("A = LOAD '" + Util.generateURI(tmpFile.toString(),
pig.getPigContext()) + "';");
pig.registerQuery("Split A into A1 if $0<=10, A2 if $0>10;");
pig.registerQuery("Store A1 into '" +
FileLocalizer.getTemporaryPath(pigContext) + "';");
pig.openIterator("A2");
{code}
The "store A1" is the 1st job, and "openIterator(A2)" is the 2nd job. Since the
input file was deleted after the 1st job, "openIterator(A2)" fails to load it.
Attached is a patch that remove "deleteTemp
Files()" from PigServer. I think having it only in GruntParser servers the
original motivation of this jira. Please let me know anyone thinks otherwise.

> When using Grunt, intermediate data and distributed caches files are left in
> 'pig.temp.dir' until the session is closed. It would be nice to cleanup files
> as they are no longer needed.
