> 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.
