=== Notes on developing a batch partitioned app for the Yarn platform
* When deploying partitioned apps on the Yarn platform be sure use the following dependency for the
Spring Cloud Yarn Deployer:
```
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-deployer-yarn</artifactId>
</dependency>
```
* Also add the following property to your application.properties: `spring.yarn.container.keepContextAlive=false`.
* When setting up environment variables for the partitions in the PartitionHandler it is recommended that you do not
copy the current working environment properties.
