Hudson commented on HBASE-5442:
-------------------------------

Integrated in HBase-TRUNK-security #122 (See [https://builds.apache.org/job/HBase-TRUNK-security/122/])
    [jira] [HBASE-5442] Use builder pattern in StoreFile and HFile

Summary: Cleaning up the factory method explosion in HFile writer and StoreFile.
Now, adding a new parameter to HFile/StoreFile writer initialization will not
require modifying factory method invocations all over the codebase.

Test Plan:
Run unit tests
Deploy to dev cluster and run a load test

> 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.
