Subject [jira] Commented: (HADOOP-2325) Require Java 6
Date Fri, 30 May 2008 16:14:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2325?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12601186#action_12601186

Doug Cutting commented on HADOOP-2325:

There is no urgency to this, but it would be nice not to delay it.

Hadoop performs better on Java 6, so we want to encourage folks to use Java 6.  The vast majority
of Hadoop contributors use Java 6 when developing, and hence do run into (usually minor) back-compatibility
problems, like the one we've just seen with HADOOP-3468.  These problems cost the project
some productivity.

On the other hand, we don't want to leave contributors behind.  It appears that Java 6 is
still not available on PowerPC-based Macs.  Sigh.  Michael, is the G4 your primary development

> We should require Java 6 for release 0.17.  Java 6 is now available for OS/X.  Hadoop
performs much better on Java 6.  And, finally, there are features of Java 6 (like 'df') that
would be nice to use.
