> Loading coprocessors classes from jar files (at hdfs or local fs) is supported from CP
framework right now. We used to have a test case to cover this scenario which uses an base-64
encoded string at the test case to represent a compiled jar file. This hardcoded way was not
acceptable as a valid test case, so we removed it eventually. 
> We need to have a better way to redo this case. Option 1) modify maven file in order
to compile a test cp class into jar, and put it to hdfs and local fs, and run the cp class
loading test; option 2) use Java 6.0 Compiler API to compile the test case at runtime and
create the jar file?
> Need more time to investigate which one is better.
