Subject Re: [DISCUSS] Set minimum version of Hadoop 3 to JDK8 (HADOOP-11858)
Date Tue, 17 May 2016 00:38:05 GMT

There’s a bunch of stuff that needs to happen at the Jenkins level:

* Kill off the JDK7 trunk builds for HADOOP, HDFS, MAPRED, YARN
* Remove JDK7 from pre-commit for HADOOP, HDFS, MAPRED, YARN

One thing that needs to happen in the Apache Yetus project:
* Wait until YETUS-369 has been written and committed to re-enable JDK7 for pre-commit  (This
effectively means that *ALL* JDK7 testing will *ONLY* be happening in the regularly scheduled
builds)

One thing that really should happen in the Apache Hadoop project:
* Remove JDK7 from trunk Dockerfile

I’ll start banging on this stuff over the next few days.
