Getting this?

There is a problem processing audits for HIVESERVER2.

[02/Sep/2019 12:36:30 +0000] 32165 Audit-Plugin throttling_logger ERROR    (341 skipped) Error occurred when sending entry to server: [02/Sep/2019 12:36:30 +0000] 32165 Audit-Plugin throttling_logger INFO     (341 skipped) Unable to send data to nav server. Will try again.

Diggig further, we see this error as well:

Redeploying the Spark config should solve this:

Execute DeployClusterClientConfig for {yarn,solr,hbase,kafka,hdfs,hive,spark_on_yarn} in parallel.

We can only surmise what may have occurred in this case.  Apparently config updates were being done to the config while an earlier config deployment was happening, corrupting the setup.  This may not solve it, however.  YMMV.  

In all likelihood, your free license has expired.  In that case navigate to Cloudera Management Service then turn off / uncheck the following:

Navigator Audit Server Role Health Test

But that wasn't it either.  Finally, remove the Navigator Audit Server from Cloudera Management Services instances since no valid license exists.
