Joseph K. Bradley updated SPARK-1215:
-------------------------------------
Comment: was deleted
(was: Just to let you know, I'll give the go-ahead for this tomorrow. Based on
Patrick's recommendation, I'm blocking on this JIRA until tomorrow to give
Prashant ( https://issues.apache.org/jira/browse/SPARK-2497 ) a chance to
fix a MIMA issue. If it's not fixed by tomorrow, then I'll get Manish to
do a temp filter workaround.
