             Summary: scala DateTimeUtilsSuite daysToMillis and millisToDays fails w/java 8 181-b13
                 Key: SPARK-24950
                 URL: https://issues.apache.org/jira/browse/SPARK-24950
             Project: Spark
          Issue Type: Bug
          Components: Build, Tests
    Affects Versions: 2.4.0
            Reporter: shane knapp


during my travails to port the spark builds to run on ubuntu 16.04LTS, i have encountered a strange and apparently java version-specific failure on *one* specific unit test.

the failure is here:

[https://amplab.cs.berkeley.edu/jenkins/job/spark-master-test-sbt-hadoop-2.6-ubuntu-test/868/testReport/junit/org.apache.spark.sql.catalyst.util/DateTimeUtilsSuite/daysToMillis_and_millisToDays/]

the java version on this worker is:

sknapp@ubuntu-testing:~$ java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

however, when i run this exact build on the other ubuntu workers, it passes.  they systems are set up (for the most part) identically except for the java version:

sknapp@amp-jenkins-staging-worker-02:~$ java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

there are some minor kernel and other package differences on these ubuntu workers, but nothing that (in my opinion) would affect this test.  i am willing to help investigate this, however.

the test also passes on the centos 6.9 workers, which have the following java version installed:

[sknapp@amp-jenkins-worker-05 ~]$ java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

my guess is that either:

sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/util/DateTimeUtils.scala

or

sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/util/DateTimeUtilsSuite.scala

is doing something wrong.  i am not a scala expert by any means, so i'd really like some help in trying to un-block the project to port the builds to ubuntu.
