Review request for Ambari, Dmitro Lisnichenko, Jonathan Hurley, Nate Cole, and
Srimanth Gunturi.
Bugs: AMBARI-9717
https://issues.apache.org/jira/browse/AMBARI-9717
Repository: ambari
Description
-------
Kafka and Spark service checks will fail intermittently.
Kafka runs a command to create a topic, which is expected to fail after being
ran once, and then greps the output to make sure that the topic was created or
already existed. The problem is that this will only work the first time, since
it was not ignorring stderr. Instead, just call the command, and perform a
regex match on the output.
Spark was not kiniting before doing its service check. I presume it worked
sometimes if some credenetial had already been cached.

Testing
-------
Deployed a 3-node cluster with HDFS, Yarn, MR, TEZ, ZK, Ranger, Kafka, and
Spark, then added Namenode HA, Kerberized the cluster, and performed an RU.
Unit tests are in progress.
Thanks,
Alejandro Fernandez
