Group permissions for files written using Crunch

[Amirdha Gopal R <am...@thoughtworks.com>]

Dear community,

The reducer part files that are written using Crunch pipelines has the
correct username but the groupname is marked as '*supergroup*', to which
the user does not belong to.

How does group membership is derived by Crunch? Also, is there a way to
specify the group information to be used for those part files in Crunch
configuration?

Thanks,
Amirdha Gopal R

It works the same way it does for MapReduce- the group is derived from the
group of the parent directory. If you need to change the group permissions
prior to writing the output, you can do something like this:
