Jonathan Turner Eagles updated TEZ-4122:
----------------------------------------
Description:
ReflectionUtils.getClazz relies on the context classloader,
{code}
clazz = Class.forName(className, true,
Thread.currentThread().getContextClassLoader());
{code}
which essentially uses the class loader from the calling thread instead of the
system class loader. For classes the need to TezClassLoader which allows the
classes to be added to the classpath at runtime, this can cause issues as the
context class loader is from the test framework.
> TestMRRJobsDAGApi should set TezClassLoader
