> When a client is creating large number of partitions, the thrift objects are 
> deserialized into Partition objects. The read method of these objects does 
> not intern the inputformat, location, outputformat which cause large number 
> of duplicate Strings in the HMS memory. We should intern these objects while 
> deserialization to reduce memory pressure.
