---------------------------------------
I did test this locally and added some tests for float case. [^HIVE-20893.patch]
Will run some Benchmark soon on our internal Cluster while tests will run on
the patch.

> As far i can tell this is not an issue for Hive yet (most of the usage of
> probing seems to be done by one thread at a time) but it is an issue of other
> users like Druid as per the following
> issue.[https://github.com/apache/incubator-druid/issues/6546]
> The fix is proposed by the author of
> [https://github.com/apache/incubator-druid/pull/6584] is to make couple of
> local fields as ThreadLocals.
> Idea looks good to me and doesn't have any perf drawbacks.
