METRON-1624 Set Profiler and Enrichment batch parameters in Ambari
METRON-1594 introduced a mechanism to control the batch size and timeout when writing records to Kafka by updating the global properties.
Both Enrichment and the Profiler write records back into Kafka. The user can independently set the batch size and timeout for each of those. Since these are global properties, the user must set these using the CLI.
```
"profiler.writer.batchSize" : 15,
"profiler.writer.batchTimeout" : 0,
"enrichment.writer.batchSize" : 15,
"enrichment.writer.batchTimeout" : 0
```
With this change, the user can now adjust these values in Ambari.
## Testing
1. Launch the development environment. Ensure alerts are visible in the Alerts UI and that the Service Check passes.
1. Open the REPL and validate the current value of the global property 'threat.triage.score.field'. The value here, the default value should be `threat:triage:score`.
```
[root@node1 ~]# source /etc/default/metron
[root@node1 ~]# $METRON_HOME/bin/stellar -z $ZOOKEEPER
Stellar, Go!
...
[Stellar]>>> globals := CONFIG_GET("GLOBAL")
{
...
"profiler.writer.batchSize" : "15",
"profiler.writer.batchTimeout" : "0",
...
"enrichment.writer.batchSize" : "15",
"enrichment.writer.batchTimeout" : "0",
...
}
```
1. Change any of these values in Ambari by going to either...
* Metron > Configs > Profiler > Kafka
* Metron > Configs > Enrichment > Kafka
1. After saving the change, Ambari should prompt for either the Profiler or Enrichment topology to be restarted
1. Restart all affected services.
1. After the services have been restarted, open the REPL and validate that the value of the global property 'threat.triage.score.field' changed in the global config.
```
[root@node1 ~]# source /etc/default/metron
[root@node1 ~]# $METRON_HOME/bin/stellar -z $ZOOKEEPER
Stellar, Go!
...
[Stellar]>>> globals := CONFIG_GET("GLOBAL")
{
...
"profiler.writer.batchSize" : "150",
"profiler.writer.batchTimeout" : "5000",
...
"enrichment.writer.batchSize" : "400",
"enrichment.writer.batchTimeout" : "10000",
...
}
```
