Sean Owen commented on SPARK-6085:
----------------------------------
Don't worry, priority doesn't mean much anyway. About 1/3rd of new JIRAs aren't
even changed from the default of "Bug - Major".
I would also like to raise the default to 10%. I would like to merge the PR in
a day or two. Any comments?
