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().The binding is done by:

...
task.context.apiProvider.GetAPIs().KubeClient.Bind(task.pod, task.nodeName)
...

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.
