Subject [jira] [Commented] (HADOOP-10530) Make hadoop trunk build on Java7+ only
Date Tue, 09 Dec 2014 20:10:15 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10530?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14239975#comment-14239975
] 

Colin Patrick McCabe commented on HADOOP-10530:
-----------------------------------------------

P.S.  One way to have improved this migration would have been to have test-patch.sh log an
error message if the jdk version was 6, rather than failing the build like maven-enforcer
plugin does. This way, we would have seen a noisy error message (but not a build failure)
for everyone who had not yet updated their precommit / postcommit / etc. job.  Then after
2 or 3 weeks we could have transitioned to maven-enforcer.  hindsight is 20/20 I guess (luckily,
so is MadDog)
