The MonitorActivity processor has a "Monitoring Scope" property that determines whether to look at a node or cluster level for flow activity. It defaults to "node," but should usually be set to "cluster" in a clustered environment to make sure that all instances of the monitored flow are checked for activity. There's a bit more information here: https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-standard-nar/1.6.0/org.apache.nifi.processors.standard.MonitorActivity/index.html ...

This looks like an issue caused by an extraneous reference to phoenix-server.jar in the YARN classpath. There's an article on that issue affecting Oozie here, and I suspect the resolution would be similar (either removing the reference or moving it to the end of the classpath): https://community.hortonworks.com/content/supportkb/167173/errornosuchmethoderror-comfacebookfb303-when-execu.html It's also possible that there's an older version of libfb303 floating around in the path somewhere. Hive should be using 0.9.3 as of the HDP 2.6.4.x stack. ... View more

If you already have SPNEGO configured correctly on the browser (e.g., native support in Mozilla/FireFox), this error can be caused if the solr host has two IP addresses and hostnames. If the local browser is using one hostname, but the solr internal hostname is different, solr will return a 401/Authentication Required. To resolve this, try accessing the alternate hostname, which may require setting up a local hosts file entry. ... View more

One last note: You'll need to update the security rules for your AWS instance. Initially, you have to add a custom TCP rule to allow traffic on port 8888 (usually - Sean's last command will tell you the port). Once you have access, the sandbox portal will give you the ports for all the other services that need to be opened up. ... View more
