> NIFI-1974 addressed this for the 0.x baseline but the PR does not apply cleanly to the 1.x baseline. Creating a separate JIRA for 1.x so that we can close out NIFI-1974 since 0.7.0 is ready to be released.
> In addition to the merge this should also include a fix to ensure that variable registry is initialized on startup that variables from the registry are applied during EL compilation based on the following order of precedence:
> 1)      Flow File Attribute
> 2)      Processor provided variables
> 3)      User Defined Variables (via custom properties)
> 4)      JVM System Properties
> 5)      OS Environment Variables
> Finally the following processor properties should be enabled to support expression language:
> Put HDFS/Get HDFS/List HDFS
> - Directory property
> ConsumeJMS/PublishJMS
> - Destination Name property
> MS Connection Factory Provider
> -MQ ConnectionFactory Implementation (fqn classname)
> -MQ client library path
> -Broker URI 
> DBCP Connection Pool: 
> -Database Connection URL
> -Database Driver Class Name
> -DB Driver jar url
> -DB username 
> -DB password
> ConvertCSVToAvro
> -add EL support for the following property
> -csv charset
> -and below...
