Swaranga Sarma created SPARK-7717:
-------------------------------------
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.
