[jira] [Commented] (HADOOP-10530) Make hadoop trunk build on Java7+
only
[ https://issues.apache.org/jira/browse/HADOOP-10530?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14034446#comment-14034446 ]
Haohui Mai commented on HADOOP-10530:
-------------------------------------
The patch looks good to me. +1.
Built hdfs on both Mac OS X and CentOS with Java 7. Work as expected.
Built with Java 6 on CentOS. Failed as expected.
Ran a few tests with hdfs and it looked pretty good to me.
This should be a low risk change since (1) it is going into trunk only, and (2) Hadoop on Java 7 has been proved in production (based on my understanding several company has been supporting Hadoop on Java 7 for a while).
This only thing left is that we need to make sure that Jenkins moves to Java 7 before this patch goes into the trunk.
