-------------------------------------

             Summary: Spark Standalone Web UI shown incorrect total memory
                 Key: SPARK-7717
                 URL: https://issues.apache.org/jira/browse/SPARK-7717
             Project: Spark
          Issue Type: Bug
          Components: Web UI
    Affects Versions: 1.3.1
         Environment: RedHat
            Reporter: Swaranga Sarma
            Priority: Minor


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 cores shown is incorrect, it shows 4*c, where "c" is the number of cores on each worker.
