-----------------------------------

             Summary: update jvm on jenkins workers
                 Key: SPARK-26282
                 URL: https://issues.apache.org/jira/browse/SPARK-26282
             Project: Spark
          Issue Type: Improvement
          Components: Build
    Affects Versions: 2.4.0
            Reporter: shane knapp
            Assignee: shane knapp


the jvm we're using to build/test spark on the centos workers is a bit...  long in the teeth:
{noformat}
[sknapp@amp-jenkins-worker-04 ~]$ 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){noformat}
on the ubuntu nodes, it's only a little bit less old:
{noformat}
sknapp@amp-jenkins-staging-worker-01:~$ 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){noformat}
steps to update on centos:
 * manually install new(er) java
 * update /etc/alternatives
 * update JJB configs and update JAVA_HOME/JAVA_BIN

steps to update on ubuntu:
 * update ansible to install newer java
 * deploy ansible

questions:
 * do we stick w/java8 for now?
 * which version is sufficient?
