> 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.
