-------------------------------
Integrated in HBase-TRUNK #2669 (See
[https://builds.apache.org/job/HBase-TRUNK/2669/])
[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

> Use builder pattern in StoreFile and HFile
> ------------------------------------------
>
> Key: HBASE-5442
> URL: https://issues.apache.org/jira/browse/HBASE-5442
> Project: HBase
> Issue Type: Improvement
> Reporter: Mikhail Bautin
> Assignee: Mikhail Bautin
> Fix For: 0.94.0
>
> Attachments: D1893.1.patch, D1893.2.patch, D1941.1.patch,
> D1941.2.patch, HFile-StoreFile-builder-2012-02-22_22_49_00.patch
>
>
> 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.
