Re: multiple instances of the same interpreter type

[Rick Moritz]

Which version of Zeppelin are you running?
There was a bug, where killing Zeppelin wouldn't actually kill the
interpreters, because the kill signal wasn't passed through, but that was
fixed in 0.7.1: https://issues.apache.org/jira/browse/ZEPPELIN-2258

Re: multiple instances of the same interpreter type

[Ruslan Dautkhanov]

We have each user running their own Zeppelin instances,
so everyone has Spark interpreter group defined as

  "option": {
..
"perNote": "shared",
"perUser": "shared",
..
  }

which translates to "interpreter will be instantiated
Globally  in shared
process."
