Hbase is not harcoded to hdfs: it works on any file system that implements the file system interface, we've run it on glusterfs for example. I assume some have also run it on s3 and other alternative file systems .
** However ** For best performance, direct block io hooks on hdfs can boost high throughout applications on hdfs. Ultimately, the hbase root directory only needs a fully qualified FileSystem uri which maps to a FileSystem class. > On Jul 14, 2014, at 5:59 PM, Ted Yu <[email protected]> wrote: > > Right. > hbase is different from Cassandra in this regard. > > >> On Mon, Jul 14, 2014 at 2:57 PM, Adaryl "Bob" Wakefield, MBA >> <[email protected]> wrote: >> Now this is different from Cassandra which does NOT use HDFS correct? >> (Sorry.
