Description

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.
