Thanks. I hadn't seen the command line upgrade instructions. I agree it's a good idea. In our case, it took nearly 4 hours to get the block report, so I wanted to make sure there was some value in having it.

The upgrade instructions call for running a block report to be used later in the process but the docs never mention it again. Why do we run a block report? I know I have no corrupt blocks.

I noticed recently a caution in the Ambari best practices document regarding clusters with more than 400 hosts. Can anyone share what I should be concerned about as I plan an upgrade to HDP 2.6.1 for a cluster with about 500 hosts?

I have a cluster with over 300 nodes. We have HA NN and three JN. I've always had the NN and JN on different hosts but recently got a suggestion to co-locate them, or at least co-locate two JN with NN, and the other JN on an unrelated host. I have co-located them in small clusters in the past, and in our dev environment they are co-located. What's the best practice?

As of sometime between Friday and yesterday afternoon, I lost the ability to see host summary data in the ambari web ui. I can click on a host and all the tabs show data except the summary tab. No error dialogs, no errors in Javascript console, nothing. It happens in all the web browsers I and my team use. Ambari version is 2.2.2.0.

I see these INFO messages frequently in datanode logs on a cluster running HDP 2.3.2. I don't see them in logs on a cluster running HDP 2.1.10. What are they trying to tell me?
