This option will set “hbase.rootdir” in hbase-site.xml and determine the directory shared by region servers and into which HBase persists. The URL should be ‘fully-qualified’ to include the filesystem scheme. If a core-site.xml is provided, the FS scheme defaults to the value of “fs.defaultFS”. Filesystems other than HDFS (like S3, QFS, Swift) are also supported.
