Alejandro Abdelnur commented on HADOOP-9426:
--------------------------------------------
JarFinder only finds (or creates if an expanded DIR) a JAR for the a class,
nothing else. ID ose not ship jars to the cluster, nor add thems them to
distributed cache, no deal with dependent jars.
You don't need to use uber-jars, you can use -libjars to push jars to the
cluster and have them in the classpath together with your job.
> Hadoop should expose Jar location utilities on its public API

> The facilities behind JobConf#setJarByClass and the JarFinder utility in test
> are both generally useful. As the core platform, these should be published as
> part of the public API. In addition to HBase, they are probably useful for
> Pig and Hive as well. See also HBASE-2588, HBASE-5317, HBASE-8140.
