Eli Levine commented on CALCITE-1561:
-------------------------------------
Thanks for disabling the tests, [~elserj]. Unfortunately these tests are coming
from local Pig and not easy to debug, since they only happen sporadically
locally. My hunch is that it has something to do with file permissions of files
Pig creates locally but finding a viable fix has been elusive. What I will do
is split up tests in the pig sub-module into unit and integration tests so only
integration tests actually run local Pig.

> I don't consider any of them serious -- they are test issues, not product
> correctness issues -- but they are inconvenient because false negatives waste
> developer time.
