Ted Yu commented on HBASE-21246:
--------------------------------
Looking at compilation errors for patch v22: 321 lines in the compilation
output.
It would be non-trivial to make v22 or v23 pass both compilation and unit test
suite.
Also, v26 is the closest to what we want WALFactory and WALProvider to be.
So it would be nice if we can build upon v26, possibly using HBASE-21456
> 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.
