> If 'hbase.wal.dir' and 'hbase.rootdir' are configured to different
> filesystem, SplitWALRemoteProcedure archived split WAL failed since
> SplitWALManager using wrong fs instance. SplitWALManager should use WAL
> corresponding fs instance.
> Steps to Reproduce:
> * Configure 'hbase.wal.dir' and 'hbase.rootdir' so that they point to
> different fs instances.
> * Start HBase with multiple RS.
> * Create a couple of tables and some rows in them so that the RSs get
> assigned with some regions.
> * Take any RS with non-zero number of regions offline.
> * Check master logs for "Wrong FS" error as shown in the screenshot
> attached.
