Thomas Graves commented on SPARK-14245:
---------------------------------------
see the commend in the PR, I think there was a race with the SparkContext
version:
I just pushed an update. I changed how I get the username so it uses the same
method for both active and history. This method actually pulls the information
from the same source as both sc.sparkUser and the API do at their root, the
system env. Except with this method we make sure we always get the correct
user; I noticed a race condition when using sc.sparkUser while finding this
solution. After starting up the master when two spark applications are started
at once, one by the user who started the master and one who didn't, both would
appear to been started by the user who started the master. This would only
happened on the first apps started, any apps started after would behave as
expected. This race condition doesn't exist with my change.
