I'm using Cloudera Enterprise v5.10.1 including Kafka. We're developing some Kafka streams applications that consumer from Kafka topics, are robust, scalable and performant. Currently these applications are being deployed using an Oozie workflow and essentially run forever (ie. I don't use a coordinator). Essentially if I want to scale it up I can just launch another instance using Oozie. My question is there a better way to deploy Kafka streams application in Cloudera v5.10.1? I know there are frameworks like Mesos, Docker, etc... but not sure how well it would fit in with Cloudera.

From what I've read SASL_PLAINTEXT allows using Kerberos for authentication but once the client is authenticated the actual session is not encrypted. So to use Kerberos and have the entire client/server session be encrypted you must use SASL_SSL and setup a keystore/trustore as well. Is this correct?

I'm using Cloudera enterprise and Kafka 0.10.x. To secure Kafka I've enabled Kerberos and configured Kafka to use the SimpleACLAuthorizer which stores ACLs in ZooKeeper. Instead of using this I'd like to check Active Directory instead to determine topic authorization. I can't seem to find an implementation. Does one exist?

I'm using Cloudera 5.4.9 enterprise edition. I've created an HBase coprocessor that is packaged up into a simple JAR. I add the coprocessor to both the Master and Region servers. What's the best way to deploy this JAR? Right now I'm uploading the JAR file to HDFS and then running a -get on each node to put the JAR file in the HBase lib directory. This doesn't scale well.
