Sergio Peña commented on HIVE-15736:
------------------------------------
[~navis] [~ashutoshc] You worked and reviewed HIVE-3990, and seems it has a
couple of bugs on the getInputSummary() regarding the InputEstimator. Could you
help me review that part to see if the fix is correct? and if the lines
commented on getInputSummary() on the patch were useful in the past? because
seems they aren't, but it might be another bug.
> Add unit tests to Utilities.getInputSummary() method for multi-threading cases

> The {{Utilities.getInputSummary}} method has a configuration to use multiple
> threads to get the content summary of tables and partitions. This
> configuration variable, {{mapred.dfsclient.parallelism.max}}, is disabled by
> default and there are no tests that validate the quality of using multi
> threads.
> This JIRA is used to add tests to such method with multiple threads and fix
> any issue found.
