FAQ
Perhaps you're not getting up-to-date libraries? Try

common> ant clean jar mvn-install
hdfs> ant veryclean jar mvn-install -Dresolvers=internal
mapreduce> ant veryclean jar -Dresolvers=internal

This works for me with the 0.21 branches.

Cheers,
Tom

I've build all the various dependencies

hadoop-commons (branch 0.21)
hadoop-hdfs (branch 0.21)
hadoop (trunk == 0.21?? there is no 0.21 branch)

and then

hadoop-mapreduce (branch 0.21)

Using it I get the following exeception:

Exception in thread "main" java.lang.NoSuchMethodError:
org.apache.hadoop.conf.Configuration.addDeprecation(Ljava/lang/String;[Ljava/lang/String;)V

at org.apache.hadoop.mapreduce.util.ConfigUtil.loadResources(ConfigUtil.java:40)
at org.apache.hadoop.mapreduce.Cluster.<clinit>(Cluster.java:64)

What's going on?

cheers
