> While implementing TezExecutionEngine, I realized that a lot of code can be
> shared between MRExecutionEngine and TezExecutionEngine because both use the
> common Hadoop framework (hdfs, resource manager, etc). So it would make sense
> to create a base abstract class for them (called HExecutionEngine) and have
> them inherit common methods and fields from it.
