Jeff Storck commented on NIFI-1586:
-----------------------------------
This issue has started to be observed again. After doing some research on
ZooKeeper's auto purge functionality, it looks like we need to start the
ZK-provided DatadirCleanupManager when the embedded ZK server is started. I'll
look into this a bit more to see if there's a better solution for ZK 3.4.6
(which we're using currently), but otherwise the DatadirCleanupManager will
solve this issue.

> Key: NIFI-1586
> URL: https://issues.apache.org/jira/browse/NIFI-1586
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.3.0
> Environment: latest 0.5.1 release
> Reporter: Matthew Clarke
>
> 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.
