Hey all,
My vote threads seem to be running about 24 hours behind and/or
getting swallowed by infra e-mail.
I sent RC8 yesterday and we might send one tonight as well. I'll make
sure to close all existing ones
There have been only small "polish" changes in the recent RC's since
RC5. So testing any off these should be pretty equivalent. I'll make
sure I close all the other threads by tonight.

Re: [VOTE] Release Apache Spark 1.0.0 (rc7)
Posted by Mark Hamstra <ma...@clearstorydata.com>.
Sorry for the duplication, but I think this is the current VOTE candidate
-- we're not voting on rc8 yet?
+1, but just barely. We've got quite a number of outstanding bugs
identified, and many of them have fixes in progress. I'd hate to see those
efforts get lost in a post-1.0.0 flood of new features targeted at 1.1.0 --
in other words, I'd like to see 1.0.1 retain a high priority relative to
1.1.0.
Looking through the unresolved JIRAs, it doesn't look like any of the
identified bugs are show-stoppers or strictly regressions (although I will
note that one that I have in progress, SPARK-1749, is a bug that we
introduced with recent work -- it's not strictly a regression because we
had equally bad but different behavior when the DAGScheduler exceptions
weren't previously being handled at all vs. being slightly mis-handled
now), so I'm not currently seeing a reason not to release.
