Matt, Yahoo testing has found 1 issue so far that we believe is a blocker in 0.20.205.0 RC-1: https://issues.apache.org/jira/browse/HDFS-2392 – distcp with hftp is failing
If there is an RC2 we would also like the following 2 JIRA to be considered as candidates: 1. https://issues.apache.org/jira/browse/MAPREDUCE-2777 – CPU usage counters 2. https://issues.apache.org/jira/browse/HDFS-2358 - NPE when the default filesystem's uri has no authority MAPREDUCE-2777 was originally included in 205 RC1 but pulled due to (I believe) unrelated unit test failures that are no longer an issue. Thanks, Scott Bush
