@zjffdu I agree about bringing security related features together in longer
term, possibly `Credentials` menu could be used for that.
Also regarding previously discussed running of `--proxy-user` with yarn
cluster mode, I believe it's currently not supported in Zeppelin. As far as I
know only standalone and yarn-client modes are supported by pure Spark
interpreter.
@Tagar right, if used in that way, kerberos tickets wouldn't be renewed
automatically. However as i said, I think Spark interpreter doesn't support
yarn cluster mode, so using `ZEPPELIN_IMPERSONATE_CMD` with `kinit` wouldn't be
required in that case.
also anyone having yarn cluster mode setup with kerberos is more than
welcome to test it :)
