>
> Currently, modifying the value of hive.fetch.task.conversion to "more"
> results in a dangerous setting where small scale queries function, but large
> scale queries crash.
> This occurs because the default threshold of -1 means apply this optimization
> for a petabyte table.
> I am testing a variety of queries with the setting "more" (to make it the
> default option as suggested by HIVE-887) change the default threshold for
> this feature to a reasonable 1Gb.
