> We have five ways to create an HFile writer, two ways to create a StoreFile writer, and
the sets of parameters keep changing, creating a lot of confusion, especially when porting
patches across branches. The same thing is happening to HColumnDescriptor. I think we should
move to a "builder pattern" solution, e.g.
> {code:java}
>   HFileWriter w = HFile.getWriterBuilder(conf, <some common args>)
>       .setParameter1(value1)
>       .setParameter2(value2)
>       ...
>       .build();
> {code}
> Each parameter setter being on its own line will make merges/cherry-pick work properly,
we will not have to even mention default parameters again, and we can eliminate a dozen impossible-to-remember
constructors.
> This particular JIRA addresses StoreFile and HFile refactoring. For HColumnDescriptor
refactoring see HBASE-5357.
