[christopherr_sp · Accepted solution]

Concerning the '/brokers/ids' error you should not run:

/opt/caspida/bin/Caspida start 

Instead, run:

/opt/caspida/bin/Caspida start-all 

'caspida start' is usually used against an individual service name. 

The documentation for this is included below for your future reference. 

https://docs.splunk.com/Documentation/UBA/4.1.2/Install/DeploymentArchitecture

An * indicates services that are started with the caspida start command and stopped with the caspida stop command. To start or stop all services, use caspida start-all or caspida stop-all. 

e.g. 

3 servers
postgresql 
caspida-jobagent* 
hive-metastore 
influxdb 
impala-server 
impala-catalog 
impala-state-store 
caspida-jobmanager* 

etc.
