https://github.com/apache/nifi/pull/1148
I have recompiled and added expression language support (with expected
evaluation on read) for both principal and keytab. However when I add any
expression language to one of such attributes (in a Hive or HDFS processor on a
kerberized Nifi instance) a tooltip says that the attribute has not been set.
It looks like some UI validation is still not recognising the expression
language as valid. How do I overcome this problem? Thank you.

> Issue Type: Improvement
> Reporter: Maurizio Colleluori
> Priority: Minor

> Kerberos properties (e.g. principal, keytab) available as attributes in
> certain processors (e.g. HDFS processors) only accept a constant value.
> Support for expression language could be enabled and allow for
> parameterisation.
