Subject RE: Switching trunk build to jdk1.7; will break some tests
Date Sat, 29 Sep 2012 21:52:40 GMT
I had problems running Hadoop CDH3U3 Pi Example with JDK1.6.0_32 on 64-bit
CentOS this Summer; this specific version of Java 6 had a bug with floating
point calculations on 64-bit Linux.
JDK1.6.0_31 works just fine (no any sensible bugs encountered)

I'll switch the trunk build to JDK7 unless objection next week.

It'll break tests.  Jimmy Xiang figured this a while ago and he filed
https://issues.apache.org/jira/browse/HBASE-6182.  He also started fixing
some of the breakage.  Lets help him out.

Some reasons to favor JDK7 are JDK6 is being EOL'd soon and JDK7 reportedly
improves performance by noticeably percentages.
