> Problem Statement : I am Using User impersonation for some of interpreters in
> zeppelin , now that the interpreters write their own logs to the zeppelin log
> directory. This becomes impossible if the users do not have permissions to
> write to the zeppelin log directory. This is because while starting zeppelin
> the Ambari changes the permission of zeppelin log directory to 0755 which
> makes only Zeppelin user having having write permission in log directory.
> expectation with user impersonation is, all the impersonating users will
> belong to hadoop group (which is same as zeppelin, zeppelin also belong to
> hadoop) . So Zeppelin Startup script should give 0775 Permission to
> /var/log/zeppelin folder
