Subject Re: [VOTE] Release Apache Spark 2.4.4 (RC1)
Date Mon, 19 Aug 2019 20:40:35 GMT
Things are looking pretty good so far, but a few notes:

I thought we might need this PR to make the 2.12 build of 2.4.x not
try to build Kafka 0.8 support, but, I'm not seeing that 2.4.x + 2.12
builds or tests it?
https://github.com/apache/spark/pull/25482
I can merge this to 2.4 shortly anyway, but not clear it affects the RC.


I'm getting one weird failure in tests:

- daysToMillis and millisToDays *** FAILED ***
  8634 did not equal 8633 Round trip of 8633 did not work in tz
sun.util.calendar.ZoneInfo[id="Kwajalein",offset=43200000,dstSavings=0,useDaylight=false,transitions=8,lastRule=null]
(DateTimeUtilsSuite.scala:683)

See https://github.com/apache/spark/pull/19234#pullrequestreview-64463435
for some context and
https://github.com/apache/spark/commit/c5b8d54c61780af6e9e157e6c855718df972efad
for a fix for a similar type of issue.

This may be quite specific to a particular version of Java 8, but I'm
testing on the latest (1.8.0_222). We can 'patch' it by allowing for
multiple correct answers here.
It may not hold up the RC unless others see the failure, but I can
work on that anyway.
