We are running Hadoop on Openstack. But have disks configured as RAID5. We get terrible disk throughput.
How do we do openstack disk configuration for JBOD in the way Hadoop likes. We are running Cisco UCS device , each server has 32 cores and 10 disks but on Openstack Hadoop layer in datanode each disk appears as one at this moment. Is there any documentation or best practices around configuring Openstack for Hadoop. I know there is Savana project but that does not shares how to do things at physical level. Thanks
