Ted Yu commented on HBASE-21246:
--------------------------------
bq. This is extracting the creation time, right?
The start time is extracted.
Good catch, rewritten in patch v21 with {{walProvider.getWALStartTime}}.
bq. to make sure we aren't breaking what he and Zach are doing
Agreed.
>From my investigation so far, there is no conflict between WAL refactoring and
>what's in place on the master branch.
With HBASE-20734, the location for WAL and recovered edits is unified. This
actually benefits WAL refactoring - we can get FileSystem from WAL Identity
(Path).
> 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.
