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:
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 "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)my guess is that either:
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.
