[SPARK-1104] kill Process in workerThread
As reported in https://spark-project.atlassian.net/browse/SPARK-1104
By @pwendell: "Sometimes due to large shuffles executors will take a long
time shutting down. In particular this can happen if large numbers of shuffle
files are around (this will be alleviated by SPARK-1103, but nonetheless...).
The symptom is you have DEAD workers sitting around in the UI and the
existing workers keep trying to re-register but can't because they've been
assumed dead."
In this patch, I add lines in the handler of InterruptedException in
workerThread of executorRunner, so that the process.destroy() and
process.waitFor() can only block the workerThread instead of blocking the
worker Actor...
