Middle Manager Node
|
|
------------------
|
|
|
|
For Middlemanager Node Configuration, see [Indexing Service Configuration](../configuration/indexing-service.html).
|
|
|
|
The middle manager node is a worker node that executes submitted tasks. Middle Managers forward tasks to peons that run in separate JVMs.
|
|
The reason we have separate JVMs for tasks is for resource and log isolation. Each [Peon](../design/peons.html) is capable of running only one task at a time, however, a middle manager may have multiple peons.
