Summary: Zeppelin UI hands to get loaded for several minutes in

distribution:Amazon 2.6.0 Applications:Hive 1.0.0, Spark 1.4.1]

Priority: Critical
I installed Zeppelin on EMR cluster this Spark using this script:
https://gist.github.com/snowindy/008f3e8b878a23c00679 (I made it myself)
When I navigate to http://localhost:8080 (I use ssh proxy) I see page is
pending to get loaded, hanged forever with white screen and spinning status.
When I did 'curl http://localhost:8080' from master host of my cluster, to
avoid network issues, I see this:
https://gist.github.com/snowindy/f7c473d813cb3f1433cc
Note there is no ending html tag, like page is not loaded fully.
I also headed to http://localhost:8080/scripts/scripts.js via browser and saw
that this JS file hands to get loaded too.
After 3-5 minutes of Zeppelin UI not loading, it starts to load okay. Since
then everything is fine.
Is it a bug with servlet container?
