Subject Re: Do I need to install Drill on each of the Hadoop data nodes or HBase RegionServer

Drillbits can be installed on all nodes or any subset.  Drill prefers to
have colocated nodes for better performance but this isn't a requirement
(e.g. Drillbit on same node as data node or regionserver).
