Mingliang Liu commented on HBASE-21181:
---------------------------------------
+1 (non-binding)
{{walDir}} and {{walArchiveDir}} dir should be managed together by the same
file system (FS). Otherwise, the WAL FS will [fail to

a {{walArchiveDir}} which is resolved on root FS. Other than that, this patch
makes sense for another more obvious reason: we archive the wal log files by
{{fs.rename()}}.
> Use the same filesystem for wal archive directory and wal directory

> when {{hbase.wal.dir}} is set to any filesystem other than the same
> filesystem used by rootDir e.g. {{hbase.wal.dir}} set to
> {{hdfs://something/wal}} and {{hbase.rootdir}} set to {{s3://something}},
> before this change, WAL archive directory ({{walArchiveDir}}) cannot be
> created and failed the WALProcedureStore on HMaster.
> The issue is that WAL archive directory was considered to be collocated with
> {{hbase.rootdir}} and creates a subdirectory under it. this logic needs to be
> updated.
