> When relaxing locality from node to rack, the {{node-locality-parameter}} is used: when scheduling opportunities for a scheduler key are more than the value of this parameter, we relax locality and try to assign the container to a node in the corresponding rack.
> On the other hand, when relaxing locality to off-switch (i.e., assign the container anywhere in the cluster), we are using a {{localityWaitFactor}}, which is computed based on the number of outstanding requests for a specific scheduler key, which is divided by the size of the cluster. 
> In case of applications that request containers in big batches (e.g., traditional MR jobs), and for relatively small clusters, the localityWaitFactor does not affect relaxing locality much.
> However, in case of applications that request containers in small batches, this load factor takes a very small value, which leads to assigning off-switch containers too soon. This situation is even more pronounced in big clusters.
> For example, if an application requests only one container per request, the locality will be relaxed after a single missed scheduling opportunity.
> The purpose of this JIRA is to rethink the way we are relaxing locality for off-switch assignments.
