> Java Object model has a bigger overhead when loading the objects into memory.
> The current way of estimating the object size by looking at the file size is not correct
and gives wrong results.Moreover due to this calculation, we are storing more than the configured
size for LRU cache.
> Improve the ObjectSize calculation by using the spark SizeEstimator utility
