> I launched a Spark master in standalone mode in one of my host and then launched 3 workers
on three different hosts. The workers successfully connected to my master and the Web UI showed
the correct details. Specifically, the Web UI correctly shows that the total memory and the
total cores available for the cluster.
> However on one of the worker, I did a "kill -9 <worker process id>" and restarted
the worker again. This time though, the master's Web UI shows incorrect total memory and number
of cores. The total memory is shown to be 4*n, where "n" is the memory in each worker. Also
the total workers is shown as 4 and the total number of cores shown is incorrect, it shows
4*c, where "c" is the number of cores on each worker.
