How can I dynamically set up an additional classpath so that jars are accessible from a hadoop tool class? I'm running my job via "hadoop jar". I need something like the "-libjars" switch which unfortunately works only for mappers and reducers, and my Tool implementations does not see jars provided by "libjars"
export "HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/path/to/my.jar && hadoop jar ..." seems making "my.jar" accessible to the Tool, but then libraries that are inside the job jar in the "/lib" folder become unaccessible.
