Review request for hbase.
Changes
-------
Fixed 2 issues commented by Ted.
Summary
-------
There is no test case for testing coprocesors class loading from hdfs or local
file system.
Add test cases for cp class loading.
It does:
- compile a cp implementation on the fly by Java compiler api
- build a jar file from the compiled classes
- copy the jar to local file system or hdfs so it can be loaded for a region
This addresses bug HBase-3516.

> Key: HBASE-3516
> URL: https://issues.apache.org/jira/browse/HBASE-3516
> Project: HBase
> Issue Type: Improvement
> Components: coprocessors
> Affects Versions: 0.90.0
> Reporter: Mingjie Lai
> Assignee: Mingjie Lai
>
> 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.
