When would you not get an empty map? It looks like if you are not using ZK
you always get an empty map. I must be missing something
> Define Session Specific Global Configuration Values in the REPL
> ---------------------------------------------------------------
>
> Key: METRON-1167
> URL: https://issues.apache.org/jira/browse/METRON-1167
> Project: Metron
> Issue Type: Improvement
> Affects Versions: 0.4.0
> Reporter: Nick Allen
> Assignee: Nick Allen
>
> Many Stellar functions accept configuration values from the Global
> configuration. When using the REPL you can load the global configuration
> values by launching the REPL with the -z option, which loads the global
> configuration stored in Zookeeper.
> The only way to modify the global configuration within the REPL currently is
> to do the following steps.
> 1. Retrieve the global configuration with conf := CONFIG_GET("global")
> 2. Alter that global configuration by modifying the JSON contained in the
> `conf` variable.
> 3. Push the new global configuration using CONFIG_PUT("global", conf)
> 4. Close and then reopen the REPL. Without restarting the REPL the new
> global configuration is not loaded.
> I want a way to do this directly in the REPL, without restarting it, and also
> in a way that does not modify the persisted global configuration in
> Zookeeper. I may be monkeying with something the REPL, but I don't want to
> break one of my live Metron topologies.
