Jerry He commented on HBASE-16455:
----------------------------------
An issue [~mbertozzi] raised a while ago was that the filenum/timestamp is an
internal WAL implementation detail, which should be hidden and not be exposed
to public.
> Provide API for obtaining highest file number among all the WAL files
> ---------------------------------------------------------------------

> Key: HBASE-16455
> URL: https://issues.apache.org/jira/browse/HBASE-16455
> Project: HBase
> Issue Type: Improvement
> Reporter: Ted Yu
> Assignee: Ted Yu
> Fix For: 2.0.0, 1.4.0
>
> Attachments: 16455.v1.txt, 16455.v2.txt
>
>
> Currently RegionServerServices has the following API:
> {code}
> WAL getWAL(HRegionInfo regionInfo) throws IOException;
> {code}
> Caller can only obtain filenum for a specific WAL.
> When multi wal is in use, we should add API for obtaining highest file number
> among all the outstanding WAL files.
> User can pass null to getWAL() method above, but the filenum for the returned
> WAL may not be the highest among all the WAL files.
> See log snippet in the first comment.
