Description

Fix in HIVE-19860 needs to be applied to

  static ConcurrentHashMap<ObjectInspector, StandardListObjectInspector>
      cachedStandardListObjectInspector = new ConcurrentHashMap<ObjectInspector, StandardListObjectInspector>();
...
  static ConcurrentHashMap<ArrayList<List<?>>, StandardStructObjectInspector> cachedStandardStructObjectInspector =
      new ConcurrentHashMap<ArrayList<List<?>>, StandardStructObjectInspector>();
...
  static ConcurrentHashMap<ArrayList<Object>, ColumnarStructObjectInspector> cachedColumnarStructObjectInspector =
      new ConcurrentHashMap<ArrayList<Object>, ColumnarStructObjectInspector>();

And possibly for

  static ConcurrentHashMap<Type, ObjectInspector> objectInspectorCache = new ConcurrentHashMap<Type, ObjectInspector>();
...
