>
> Observed that embedded NiFi zookeeper disk utilization will grow unbounded.  
> Zookeeper will occasional create snapshots but at no time will it ever purge 
> any of those snapshots it creates. This behavior is documented here:
> https://zookeeper.apache.org/doc/r3.1.2/zookeeperAdmin.html#sc_administering
> It is the operators responsibility to purge old snapshot files. NiFi needs to 
> provide a configuration that will automate this pruge.
