running the ant build in mapreduce on the latest 23 branch fails. Looks like the ivy properties file still has 0.24.0 and then the gridmix dependencies need to have rumen as dependency.
The gridmix errors look like:
[javac] /home/tgraves/anttest/hadoop-mapreduce-project/src/contrib/gridmix/src/java/org/apache/hadoop/mapred/gridmix/DistributedCacheEmulator.java:249: cannot find symbol
[javac] symbol : class JobStoryProducer
[javac] location: class org.apache.hadoop.mapred.gridmix.DistributedCacheEmulator
