    Remove this properties reference and instead use explicit version 
references for all the nifi version references.  Otherwise it creates problems 
during the release process.  The release plugin will take care of automatically 
bumping version numbers for us so please use 1.5.0-SNAPSHOT everywhere 
explicitly rather than ${nifi.version}

>
> Implement a PutDruid Processor and Controller using Tranquility API. This 
> will enable Nifi to index contents of flow files in Druid. The implementation 
> should also be able to handle late arriving data (event timestamp points to 
> Druid indexing task that has closed, segment granularity and grace window 
> period expired). Late arriving data is typically dropped. Nifi should allow 
> late arriving data to be diverted to FAILED or DROPPED relationship. That 
> would allow late arriving data to be stored on HDFS or S3 until a re-indexing 
> task can merge it into the correct segment in deep storage.
