Description

Despite the documentation saying that the PutElasticsearchHttp processor should support expression language this isn't happening. The Index property works correctly however. The property validates whether the value looks like a URL. But it seems like this validation is taking place before the expression is evaluated. Also, expressions like 'http://${url}' still are not evaluated.

Technically I guess this isn't a 'major' issue, but it is quite painful to use it without the replacement happening. See also NIFI-4396 which is very similar behaviour.
