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 the HColumnDescriptor refactoring.
