> CONFIG_GET Fails to Retrieve Latest Config When Run in Zeppelin REPL
> --------------------------------------------------------------------
>
> Key: METRON-1529
> URL: https://issues.apache.org/jira/browse/METRON-1529
> Project: Metron
> Issue Type: Bug
> Reporter: Nick Allen
> Assignee: Nick Allen
> Priority: Minor
>
> The configuration values retrieve by CONFIG_GET are incorrect when run in the
> Zeppelin REPL. The cache backing CONFIG_GET retrieves the correct value when
> the function is initialized. If the value is changed either in the same
> session or by an external process, the cache is never updated to the latest
> value. Restarting the Zeppelin REPL session and forcing reinitialization
> will cause the correct, latest value to be retrieved.
> Do the following in a Zeppelin Notebook to replicate the bug.
> 1. Follow the README to install the Stellar Zeppelin Interpreter.
> 2. In Zeppelin > Interpreters > Stellar, set the zookeeper URL property.
> {code}
> zookeeper.url = localhost:2181
> {code}
> 3. In Zeppelin > Interpreters > Stellar, set the following additional
> dependencies.
> | artifact | exclude
> |
> | org.apache.metron:metron-management:0.4.3 |
> |
> | org.apache.metron:metron-common:0.4.3 |
> |
> | io.thekraken:grok:0.1.0 |
> org.apache.commons:commons-lang3 |
> | org.apache.commons:commons-lang3:3.2 |
> |
>
>
> 4. Create a notebook and run the following.
> {code}
> CONFIG_GET("GLOBAL")
> {
> "k6" : "v6"
> }
> {code}
> {code}
> CONFIG_PUT("GLOBAL", '{ "k7":"v7" }')
> {code}
> {code}
> CONFIG_GET("GLOBAL")
> {
> "k6" : "v6"
> }
> {code}
> 5. The last result shold be "k7"/"v7", but is instead the old value "k6"/"v6".
