Summary: Upgrade to Spark 2.2.0
Key: KUDU-2104
URL: https://issues.apache.org/jira/browse/KUDU-2104
Project: Kudu
Issue Type: Improvement
Components: java
Affects Versions: 1.4.0
Reporter: Grant Henke
Assignee: Grant Henke
We should upgrade to Spark 2.2.0 to stay current. However, Spark 2.2 has
dropped support for Java 7. (See more details in the release notes
[here|https://spark.apache.org/releases/spark-release-2-2-0.html] and the jira
SPARK-19493)
As discussed on the dev mailing list
([here|http://search-hadoop.com/m/Kudu/Sa4NE1MRvOG1Fmhfs1?subj=Java+7+and+Spark+Support])
we should upgrade and document that the Spark 2 modules require JDK 8.
Additionally we will need to use JDK 8 when running the Jenkins build.
