>From post to hbase-dev:

I'm seeing ClassNotFoundExceptions when running ImportTsv against trunk. Presumably the old
instructions for classpath assembly need an update. I guess I could create a hadoop jar that
ships the classpath entries in lib, but IMHO that's not a viable solution for users who want
to run one of the jobs we distribute. Am I missing something?

For you reference:

{code}
$ HADOOP_CLASSPATH=$(./bin/hbase classpath) hadoop jar ./hbase-server/target/hbase-server-0.95-SNAPSHOT.jar
importtsv -Dimporttsv.columns=HBASE_ROW_KEY,d:c1,d:c2 -Dimporttsv.bulk.output=hdfs:///tmp/hfiles
simple hdfs:///tmp/simple.tsv

...
