Spark Master Web UI showing "0 cores" in Completed Applications table

Question asked by vsbgugan on Mar 16, 2015
I have a question about the "Completed Applications" table on the Spark
Master web UI page.

For the column "Cores", it used to show the number of cores used in the
application. However, after I added a line "sparkContext.stop()" as the end
my spark app, it shows "0 cores".

My application is working perfectly fine, when it is running, the "Running
Applications" table shows that it is using "8 Cores". But once it is ended,
the "Completed Applications" page show "0 Cores".

Has anyone experienced similar issue?
