I have a spark (version 2.2.0) cluster with 7 nodes and url spark://master:7077. I setup Apache Zeppelin 0.7.2 on the master node using the following configuration:

zeppelin.env.sh

export JAVA_HOME=/usr/local/java/jdk1.8.0_144
export SPARK_HOME=/usr/local/spark-2.2.0
export MASTER=spark://master:7077
export ZEPPELIN_PORT=8082

In zeppelin-site.xml I changed zeppelin.server.port from 8080 to 8082, also tried with other ports like 8090, 8091. After starting zeppelin when I try to access web UI using master:8082 I got the following error but zeppelin status shows it is running:

HTTP ERROR: 500
Problem accessing /. Reason: javax.servlet.HttpServletRequest.isAsyncStarted()Z

I checked the logs and found that java.lang.NoSuchMethodError:javax.servlet.HttpServletRequest.isAsyncStarted()Z

Hi, 0.7.2 doesn't support spark 2.2 https://stackoverflow.com/questions/45789231/zeppelin-0-7-2-version-does-not-support-spark-2-2-0/45791664#45791664 – 1ambda Aug 29 '17 at 01:39
and Could you try changing `zeppelin.server.port` without `export ZEPPELIN_PORT=8082`? – 1ambda Aug 29 '17 at 01:39

Version compatibility I guess. It works with spark 2.1.0. – Abir Chokraborty Aug 29 '17 at 03:25
Sorry, I did a silly mistake and UI is showing now. – Abir Chokraborty Aug 29 '17 at 03:41
good to hear that it works! :) – 1ambda Aug 29 '17 at 04:36
