Ok, so I send to `localhost:8082/druid/v2` a request from the examples of the extension's website page to test if it's working and I am getting back:
```
{
"error": "Unknown exception",
"errorMessage": "org.apache.druid.java.util.common.NonnullPair cannot be cast to java.util.concurrent.ConcurrentHashMap",
"errorClass": "java.lang.ClassCastException",
"host": null
}
```

Hello,
I try to load the extension to the broker but when I start druid, it seems that it isn't loading because the queryType doesn't exist.
I am using version 0.21.0 but I have used previous ones as well. The result is unfortunately the same.
In the `conf/druid/broker/runtime.properties` file, I added `druid.extensions.loadList=["moving-average-query"]` at the top.
I am using the micro-quickstart configuration and I haven't changed anything else from there.
Java version (if for some reason that's what causes it): openjdk 1.8.0_292
I would be glad if someone could help.
Thanks in advance!

@FrankChen021 thanks for the reply.
It seems that, indeed, the broker loads the extension.
However, how do I send queries to the broker? Is there a way from the web-based UI?

Looks like there's a bug. I will investigate it later.

queries can't be sent to broker from the web console. You could find the broker IP address on the Services Tab on web console,and send queries to that address.

Assuming you have your configuration files laid out in the [recommended manner](http://druid.apache.org/docs/latest/configuration/index.html), just add the moving average extension to the `druid.extensions.loadList` in `conf/druid/broker/runtime.properties` as opposed to `conf/druid/_common/common.runtime.properties`.

@Kinigopoulos there're something you could check:
1. check the log of broker to make sure the extension has been loaded
2. make sure the query is sent to broker instead of druid router
