We've been using ext4 for HDFS and MR spill space (the rest are ext3) on CentOS 5.5 in some form or another for almost a year now.  No issues to report, other than it isn't ZFS (so we lost some functionality that we greatly miss).

At this point, we're waiting for 6.1 or 6.2 before changing our Linux version.   RH (historically) has too much shift between 0->1->2 for it to be considered stable until the .2 release.  But we might jump on .1 anyway.
