Description
Currently the ContainerScheduler in the NM picks the next queued opportunistic container to be executed in a FIFO manner. That is, we first execute containers that arrived first at the NM.
This JIRA proposes to add pluggable queue reordering strategies at the NM that will dynamically determine which opportunistic container will be executed next.
For example, we can choose to prioritize containers that belong to jobs which are closer to completion, or containers that are short-running (if such information is available).
