Hung Tran updated GOBBLIN-762:
------------------------------
Description:
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.
