> hiveserver2 is start seeing the memory pressure once the cachedUnionStructObjectInspector
start going 
> [https://github.com/apache/hive/blob/master/serde/src/java/org/apache/hadoop/hive/serde2/objectinspector/ObjectInspectorFactory.java#L345]
> I did not see any eviction policy for cachedUnionStructObjectInspector, so we should
implement some size or time-based eviction policy.
