---------------------------------------
Github user vijikarthi commented on the issue:
https://github.com/apache/flink/pull/2275
@mxm The issue is apparently due to ZK client API implementation which
lookup the system configuration property to determined the type of event
(SASLAuthenticated/SysConnected) that it should wait for? I have fixed the
issue by adding a dummy configuration file that will be used only to set the
system property when SASL authentication is enabled (Apparently both Kafka and
ZK rely on the configuration property and I believe they are moving away from
using these variables, but for now we need the hack for secure deployment).
Please take a look at the two new commits to find the fix details and I will
squash the commits after your review. Travis build is not failing anymore.
