             Summary: Refine WAL interface
                 Key: HBASE-6931
                 URL: https://issues.apache.org/jira/browse/HBASE-6931
             Project: HBase
          Issue Type: Improvement
            Reporter: Flavio Junqueira


We have transformed HLog into an interface and created FSHLog to contain the 
current implementation of HLog in HBASE-5937. In that patch, we have 
essentially exposed the public methods, moved method implementations to FSHLog, 
created a factory for HLog, and moved static methods to HLogUtil. 

In this umbrella jira, the idea is to refine the WAL interface, making it not 
dependent upon a file system as it is currently. The high-level idea is to 
revisit the methods in HLog and HLogUtil and come up an interface that can 
accommodate other backends, such as BookKeeper. Another major task here is to 
decide what to do with the splitter.
