@Leemoonsoo The latest commits seems to be working. I could see two
different SC getting created in "isolated" mode. However when the second
SparkContext is getting created, I am hitting an exception which is related to
"SPARK-10872"
Regarding proxy user support, I am not sure if we can handle it inside
"SparkInterpreter". The way spark-submit handles proxy-user is by running the
main process itself as the proxy user (see
https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala#L160).
In our case if we run the "RemoteInterpreterServer" as the proxy user, the
rest of the flow is kind of taken care automatically. I have tested
with/without Kerberos (by adding SPARK_SUBMIT_OPTIONS="--proxy-user vijay -v"
in bin/zeppelin-env.sh) and it works fine.
