@Constantin Stanca Command worked. I have some bad blocks, but it is not a big deal. This is my sandbox environment. Lesson learned to take a cold backup. Thank you so much!

I restored my HDP 2.6.4 cluster from instance snapshots, restarted and most of services started successfully. After a quick investigation found out that NN is in safe mode. Ok. Let's take it out of that mode with: hdfs dfsadmin -safemode leave Not so quick, it the command execution would report: Safe mode is OFF. Let me search for a forceful exit. I could not find the command. Please help.

@Constantin Stanca This is very helpful. My prototype will account for these differences. I agree with support aspects, but it is a balance between operational complexity and functionality.

We recently moved our HDP cluster to Google Cloud. We are not using any of the GC services, but we consider our options. We could continue to use HBase or migrate to BigTable. Our challenge is that we may have to change our applications using HBase as a data store. Could you advise on a safe path approach, if any?

@Zachary Brown Kafka REST api did not make it yet. See JIRA mentioned by Artem. Kafka REST proxy is included with Confluent Kafka.

@Michael Young,@lgeorge,@Constantin Stanca Wow! That was quick! Thanks so much all of you. I voted-up all your responses and choose Constantin's for the example which was very explicit and easy to follow.

I learned recently that Kafka 0.10 supports rack awareness. I researched Kafka wiki and JIRA and got some understanding, but it would be great if any of the HCC experts could provide an example of how replication works with rack awareness.
