Hi Sujee, You are correct that MapR's filesystem supports random read / write and updating in place. However, HBase was written for HDFS interfaces which don't allow modifying existing files.
That said, there are a number of features of our filesystem that can be used via HBase (e.g. snapshots, mirroring), as well as our usual management features. Here's a link to some HBase slides we presented a few months back that provides a few more details: http://www.slideshare.net/tshiran1/hbase-with-mapr -Jason On Mon, Jul 23, 2012 at 2:24 PM, Sujee Maniyam <[email protected]> wrote: > i understand currently Hbase does append on HDFS, b/c HDFS doesn't allow > random seek + modification. > > how will a file system that provides random seek+modify benefit hbase? > > Does HBase do anything special to take advantage of MapR file sytem (which > I _think_ supports random r/w) > > just curious > > thanks > Sujee > > http://sujee.net >
