Review comment:
True, I'll remove the unused `resource`.
For the memory size checking, it is guaranteed by Yarn that the allocated
container should have at least requested memory size, or otherwise the request
will not be satisfied. But I think it doesn't harm to add an assertion for
double checking.
Agree that in future we can have some smarter way to match pending task
executor resource, so we can leverage the extra memory allocated in the
container.
