+Storm now has 4 kinds of build-in schedulers:
[DefaultScheduler](https://github.com/apache/storm/blob/1.x-branch/storm-core/src/clj/org/apache/storm/scheduler/DefaultScheduler.clj),
[IsolationScheduler](https://github.com/apache/storm/blob/1.x-branch/storm-core/src/clj/org/apache/storm/scheduler/IsolationScheduler.clj),
[MultitenantScheduler](https://github.com/apache/storm/blob/1.x-branch/storm-core/src/jvm/org/apache/storm/scheduler/multitenant/MultitenantScheduler.java),
[ResourceAwareScheduler](Resource_Aware_Scheduler_overview.html).
+
+## Pluggable scheduler
+You can implement your own scheduler to replace the default scheduler to
assign executors to workers. You configure the class to use using the
"storm.scheduler" config in your storm.yaml, and your scheduler must implement
[this
interface](https://github.com/apache/storm/tree/1.x-branch/storm-core/src/jvm/org/apache/storm/scheduler/IScheduler.java).
