Thx @kayousterhout for the ping !
We are fairly aggressively using blacklisting executors - not hosts.
The assumption that a task failed on an executor in a host will imply it
will fail on all executors on the host is incorrect - particularly in
multi-tennet environment : where number of executors per host can be fairly
high : which is exactly the reason why I added this hack to begin with.
Instead of modifying the existing behavior of executor level blacklist, it
would be better to add to it - add a way to configure host level blacklisting
in addition to existing functionality.
I am -1 on changing the existing behavior.
