Thanks for your response.
i've tried to add `MinionEventObserver`  file but i am not able to register it. can you please help me to register?

follow the doc:
```Plug-in Custom Tasks
To plug in a custom task, implement PinotTaskGenerator, PinotTaskExecutorFactory and MinionEventObserverFactory (optional) for the task type (all of them should return the same string for getTaskType()), and annotate them with the following annotations:

After annotating the classes, put them under the package of name org.apache.pinot.*.plugin.minion.tasks.*, then they will be auto-registered by the controller and minion.
Example
See SimpleMinionClusterIntegrationTest where the TestTask is plugged-in.```


yeah, i've implemented these three task and its working perfectly but there is no tag for `MinionEventObserver`

take an example of <https://github.com/apache/pinot/tree/master/pinot-plugins/pinot-minion-tasks/pinot-minion-builtin-tasks/src/main/java/org/apache/pinot/plugin/minion/tasks/purge|https://github.com/apache/pinot/tree/master/pinot-plugins/pinot-minion-tasks/pinot[…]-tasks/src/main/java/org/apache/pinot/plugin/minion/tasks/purge>

thats for factory which i've already mention in factory file

there are two interface
```MinionEventObserverFactory and MinionEventObserver```

got a solution for this:
tag is not there for `MinionEventObserver`  we have to create a object in `MinionEventObserverFactory`  to create observer.
