It looks like a ssh problem. Can you tell me the setting how we use Spark Interpreter?

Re: what causes InterpreterException: Host key verification failed

Dominik
In reply to this post by Yeshwanth Jagini
The impersonation feature of Zeppelin is currently based per default on SSH-ing to localhost:

  https://zeppelin.apache.org/docs/0.7.0/manual/userimpersonation.html

This can be overridden e.g. by setting ZEPPELIN_IMPERSONATE_CMD as env variable (e.g. for sudo), but the above error you are reporting sounds like you are trying to use impersonation without having set up the underlying SSH infrastructure.

Re: what causes InterpreterException: Host key verification failed

Arun Natva
If you are using zeppelin 0.7.0, the easiest way is to use Livy interpreter and get rid of the zeppelin impersonate CMD confit from zeppelin-env

Livy interpreter supports user impersonation. You can use Livy.spark, livy.pyspark, livy.sql interpreters

Re: what causes InterpreterException: Host key verification failed

Yeshwanth Jagini
i am using livy interpreter, i don't have any issues now.
it's bit confusing whole impersonation on interpreter level and then on the spark yarn  level.
we should have some good documentation explaining this.
how can i contribute to documentation?

If you are using zeppelin 0.7.0, the easiest way is to use Livy interpreter and get rid of the zeppelin impersonate CMD confit from zeppelin-env

Livy interpreter supports user impersonation. You can use Livy.spark, livy.pyspark, livy.sql interpreters
