> Path archivedLogLocation = new Path(oldLogDir, path.getName());
> final FileSystem fs = CommonFSUtils.getWALFileSystem(conf);
> if (fs.exists(archivedLogLocation)) {
> LOG.info("Log " + path + " was moved to " + archivedLogLocation);

> [ReplicationSource#getFileSize|https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/replication/regionserver/ReplicationSource.java#L399]

> All of the above calls are trying to find the log in archive path after they couldn't locate the wal in walsDir and they are not used for moving a log file to archive directory.
> But we will look for archive path within serverName directory only if conf key is true.
