Hi Ted,

Any thoughts on this ???

I am getting the same kind of error when I kill a worker on one of the
machines.
Even after killing the worker using kill -9 command, the executor shows up
on the spark UI with negative active tasks.

All the tasks on that worker starts to fail with the following exception.


16/04/01 23:54:20 WARN TaskSetManager: Lost task 141.0 in stage 19859.0
