Subject [jira] [Commented] (HADOOP-11090) [Umbrella] Support Java 8 in Hadoop
Date Tue, 21 Jul 2015 18:13:09 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14635530#comment-14635530
] 

Robert Kanter commented on HADOOP-11090:
----------------------------------------

The nightly JDK8 builds are definitely in a better state than they were before.  Common has
been mostly green now, MR was until yesterday, and YARN has been mostly green lately too.
 HDFS's build still needs some work though.

That said, I'm not sure it makes sense to wait for all of these builds to be green before
switching over.  With the number of commits going into Hadoop each day, we're basically trying
to hit a moving target here.  I think we might be better of switching the pre-commit build
to JDK8 so that we can catch anything before it goes in.  And I guess we should probably get
YARN-3528 moving again as well.
