distribution of roles across servers and architecture

I recently moved around my services and my hive queries are horribly slow now.

Is there something obvious that I have missed out on or have misunderstood.

2 of my nodes only have node managers on them without HDFS and one of my nodes have only HDFS and no node manager. Could this have resulted in slowing down of the services?
