Description

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.
