Mark Payne commented on NIFI-1586:
----------------------------------
[~msclarke] - The documentation that you're pointing to is from version 3.1.2
of Zookeeper. NiFi is running 3.4.6. In 3.4, they added the ability to
automatically purge that, but it is set to only run every 24 hours by default:
https://zookeeper.apache.org/doc/trunk/zookeeperAdmin.html
This is configured in the zookeeper.properties file with the following
properties:
autopurge.snapRetainCount
autopurge.purgeInterval
> embedded zookeeper disk utilization grows unbounded

> Key: NIFI-1586
> URL: https://issues.apache.org/jira/browse/NIFI-1586
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 0.4.1
> 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.
