   I ran through the testing instructions and hit some problems with the Batch Profiler.  First error I ran into was this:
   ```
   19/07/29 21:47:31 INFO BatchProfilerCLI: Loading profiles from '/usr/metron/0.7.2/config/zookeeper/profiler.json'
   Exception in thread "main" com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `org.apache.metron.common.configuration.profiler.ProfileResult` (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('count')
    at [Source: (String)"{
     "profiles": [
       {
         "profile": "hello-world",
         "foreach": "'global'",
         "init":    { "count": "0" },
         "update":  { "count": "count + 1" },
         "result":  "count"
       }
     ],
     "timestampField": "timestamp"
   }
   "; line: 8, column: 18] (through reference chain: org.apache.metron.common.configuration.profiler.ProfilerConfig["profiles"]->java.util.ArrayList[0]->org.apache.metron.common.configuration.profiler.ProfileConfig["result"])
   
   ```
   The same `profiler.json` deserializes without issue in the integration tests.  I suspect it is caused by a jackson version problem.  When I update `profiler.json` to:
   ```
   {
     "profiles": [
       {
         "profile": "hello-world",
         "foreach": "'global'",
         "init":    { "count": "0" },
         "update":  { "count": "count + 1" },
         "result":  { "profile": "count" }
        }
     ],
     "timestampField": "timestamp"
   }
   ```
   I am able to get past that error but then I run into this error:
   ```
   19/07/29 21:50:42 INFO StateStoreCoordinatorRef: Registered StateStoreCoordinator endpoint
