>          Issue Type: Bug
>    Affects Versions: 2.2.0, 3.0.0, 2.4.0
>            Reporter: Mithun Radhakrishnan
>            Assignee: Mithun Radhakrishnan

> Another one on behalf of [~selinazh] and [~cdrome]. Following the example in [Apache
Tez's {{MapProcessor}}|],
{{TezProcessor}} ought to use {{ProgressHelper}} to report progress for a Tez task. As per
[~kshukla]'s advice,
> {quote}
> Tez... provides {{getProgress()}} API for {{AbstractLogicalInput(s)}} which will give
the correct progress value for a given Input. The TezProcessor(s) in Hive should use this
to do something similar to what MapProcessor in Tez does today, which is use/override ProgressHelper
to get the input progress and then set the progress on the processorContext.
> ...
> The default behavior of the ProgressHelper class sets the processor progress to be the
average of progress values from all inputs.
> {quote}
> This code is -whacked from- *inspired by* {{MapProcessor}}'s use of {{ProgressHelper}}.
