Implementation Notes:

• After a "task" allocation ask is successfully handled by the core scheduler and a node is found for it, the actual binding of the Kubernetes Pod to Node is handled in cache.Task#postTaskAllocated().

Status

The attempt to build the executable on Mac and cross-compile for linux/amd64 produced an executable that yields:

exec /yunikorn-scheduler: no such file or directory

in the container. Probably the format is not correct.
