> -----------------------------------------
>
> Key: GOBBLIN-762
> URL: https://issues.apache.org/jira/browse/GOBBLIN-762
> Project: Apache Gobblin
> Issue Type: Task
> Reporter: Hung Tran
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Gobblin on YARN needs a way to scale up and down the containers based on the
> workload.
> Added `YarnAutoScalingManager` which can be started by the
> `GobblinApplicationMaster` by setting the
> `gobblin.yarn.app.master.serviceClasses` configuration. This class runs a
> scheduled task with a default interval of 60 seconds to detect the number of
> required partitions for the workflows submitted to Helix. It will request the
> `YarnService` to scale to a computed number of containers. If the requested
> number of containers is higher than the YarnService has previously requested
> then it will request more containers. If the requested count is less than the
> current number of allocated containers then it will free any unused
> containers.
