Description

Tried performing a grant from the Impala shell in a kerberized cluster with Ranger enabled and got a strange error message:

```[nightly7x-2:21000] default> grant all on table t to group asdf;
Query: grant all on table t to group asdf
Query submitted at: 2019-05-15 11:24:20 (Coordinator: https://nightly7x-2.vpc.cloudera.com:25000)
ERROR: InternalException: HTTP 400 Error: [e-mail] is Not Found
```

Not sure what's going on here
