> When conversion is minimal, simple fetch can be used only when filter on
> partition column or no filter at all. But it lead to simple fetch even if
> filter on non-partition column. Unit test " select * from srcpart where key >
> 100 limit 10 " in the nonmr_fetch.q demonstration this issue – the unit test
> is not correct indeed(it should be Map Reduce but in test it is Simple
> Fetch).
> This issue lead to a serious problem when data size is huge. When conversion
> is more and filter on both partition column and non-partition column, it will
> not chech hive.fetch.task.conversion.threshold, which lead to the query to
> takes hours to finish. This issue doesn't exist in 1.2.1, how it works should
> be a magic...
