> Key: HIVE-17576
> URL: https://issues.apache.org/jira/browse/HIVE-17576
> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.2.0, 3.0.0, 2.4.0
> Reporter: Mithun Radhakrishnan
> Assignee: Chris Drome
> Attachments: HIVE-17576.1.patch

>
> Another one on behalf of [~selinazh] and [~cdrome]. Following the example in
> [Apache Tez's
> {{MapProcessor}}|https://github.com/apache/tez/blob/247719d7314232f680f028f4e1a19370ffb7b1bb/tez-mapreduce/src/main/java/org/apache/tez/mapreduce/processor/map/MapProcessor.java#L88],
> {{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}}.
