Prashant Kommireddi commented on PIG-2582:
------------------------------------------
Hey Prasanth, the reason is that we don't want to break backward compatibility
in case these member variables are accessed directly and not through getters.
There are no such references from within the Pig project, but I'm being wary of
any users who use this from outside of it.
The interface stability is marked Unstable on this, so I am ok if all decide
its cool to change the scope of these variables :)
> Store size in bytes (not mbytes) in ResourceStatistics

> Project: Pig
> Issue Type: Bug

> In
> [ResourceStatistics.java|http://svn.apache.org/viewvc/pig/trunk/src/org/apache/pig/ResourceStatistics.java?view=markup]
> we see mBytes is public, and has a public getter/setter.
> {code}
> 47 public Long mBytes; // size in megabytes
> 196 public Long getmBytes() {
> 197 return mBytes;
> 198 }
> 199 public ResourceStatistics setmBytes(Long mBytes) {
> 200 this.mBytes = mBytes;
> 201 return this;
> 202 }
> {code}
> Typically sizes are stored as bytes, potentially having convenience functions
> to return with different units.
> If mBytes can be marked private without causing woes it might be worth
> storing size as bytes instead.
