** Restarting a dead service on a node
https://aws.amazon.com/premiumsupport/knowledge-center/restart-service-emr/

hbase regionserver logs were saying they were timing out talking to hdfs ports.
This led us to a problem with the "datanode" service, and that above blog about restarting services is how we restarted that service.

Just looking through these will help to find what's broken.
