[2/2] spark git commit: [SPARK-3873][MLLIB] Import order fixes.
Posted by rx...@apache.org.
[SPARK-3873][MLLIB] Import order fixes.
A slight adjustment to the checker configuration was needed; there is
a handful of warnings still left, but those are because of a bug in
the checker that I'll fix separately (before enabling errors for the
checker, of course).
Author: Marcelo Vanzin <va...@cloudera.com>
Closes #10535 from vanzin/SPARK-3873-mllib.
