Ted Yu commented on HBASE-21246:
--------------------------------
In patch v24, I dropped the static methods from WALFactory - there are used in
test code.
I also removed reference to AbstractFSWALProvider since the Reader creation is
done by the provider.
> Introduce WALIdentity interface

> We are introducing WALIdentity interface so that the WAL representation can
> be decoupled from distributed filesystem.
> The interface provides getName method whose return value can represent
> filename in distributed filesystem environment or, the name of the stream
> when the WAL is backed by log stream.
