> Note: I am not an expert at JAVA, Class loaders, or Hadoop. I am just a
> hacker. My solution might be entirely wrong.
> AbstractMapWritable.readFields throws a ClassNotFoundException when reading
> custom writables. Debugging the job using remote debugging in IntelliJ
> revealed that the class loader being used in Class.forName() is different
> than that used by the Thread's current context
> (Thread.currentThread().getContextClassLoader()). The class path for the
> system class loader does not include the libraries of the job jar. However,
> the class path for the context class loader does. The proposed patch changes
> the class loading mechanism in readFields to use the Thread's context class
> loader instead of the system's default class loader.
