> In FSEditLog,
> - long and short are first converted to String and are further converted to
> UTF8
> - For some non-array items, it first create an ArrayWritable object to hold
> all the items and then writes the ArrayWritable object.
> These result creating many intermediate objects which affects Namenode CPU
> performance and Namenode restart.
