Description

Zeppelin Interpreter settings are getting updated after zeppelin restart.
Live cluster : http://ctr-e135-1512069032975-20895-02-000009.hwx.site:9995/#/interpreter
Steps to reproduce :
1) Update the zeppelin.pyspark.python to /base/tools/python-2.7.14/bin/python for spark2 interpreter
2) Restart zeppelin
3) After restart zeppelin.pyspark.python is getting overridden with value 'python'.
Same is observed with livy2 interpreter.

But same steps for spark interpreter is working fine even after zeppelin restart.

So looks like issue is happening only for spark2 and livy2 interpreter.

Seeing below error in zeppelin logs :
