> During the first region opens on the RS, WALFactory will create a WAL file, but if the wal creation fails, in some cases, HDFS will leave a empty file in the dir(e.g. disk full, file is created succesfully but block allocation fails). We have a check in AbstractFSWAL that if WAL belong to the same factory exists, then a error will be throw. Thus, the region can never be open on this RS later.
