>
> YARN Node labels were introduced in Hadoop version 2.6, which allows to group
> nodes with similar characteristics and allows applications to specify where
> to run. This patch adds support for YARN node labels in Samza.
> In this implementation, node labels are defined directly in yarnConfig in
> YarnClusterResourceManager. It might be better to have node labels as a part
> of SamzaResourceRequest and SamzaResource classes, but
> org.apache.hadoop.yarn.api.records.Container class doesn't contain node label
> and hence we have nothing to pass to the SamzaResource constructor in
> onContainersAllocated method of YarnClusterResourceManager class.
