> GenericUDTFJSONTuple's json cache could overgrow beyond its limit

> At the moment the [cache
> object|https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDTFJSONTuple.java#L96]
> used in {{GenericUDTFJSONTuple}} is a static linked hashmap that is not
> thread-safe. In the case of HoS it may be accessed concurrently and has race
> conditions. In particular, its size may overgrow even though the limit is 32.
> This can be observed from the attached image.
> An easy way to fix it is to make it non-static.
