I'm working in a HDP-3.1.0.0 environment, the HDFS version I'm using is the 3.1.1.3.1, the cluster is composed by 2 Namenodes and 4 Datanodes. After a reboot of the HDP services (stop all and start all), the cluster seems working well, but I see the following alert:
How can I investigate this problem?
The services in my cluster don't have problems, except from the HBase Region Servers (0/4 live) and the Ambari Metrics Collector. I'm not using Hbase, so I didn't pay attention to it, could it be the root cause? I have tried to start the Ambari Metrics Collector but it always fails.
