Till Rohrmann commented on FLINK-19532:
---------------------------------------

Hi [~mlevar], thanks for reporting this issue. I think the answer to your question is that {{FlinkZooKeeperQuorumPeer}} is not really meant for production use cases and more of a utility to quickly setup a ZooKeeper cluster.

Nevertheless, I think that exposing this configuration option for the {{FlinkZooKeeperQuorumPeer}} would still improve the situation and make it more usable for long time usage of ZK started via Flink's scripts.

Do you want to work on this new feature?

> After noticing the snapshot/log buildup in our ZooKeeper {{dataDir}}, we tried enabling the purge settings ({{autopurge.snapRetainCount}} and autopurge.purgeInterval).
> Flink's {{FlinkZooKeeperQuorumPeer}} ignores the portion of {{QuorumPeerMain}} which uses those settings and starts up the {{DatadirCleanupManager}}, using only the {{runFromConfig}} method.
> Is this intentional and is the recommended way to handle snapshot buildup with the built in ZooKeeper to use the {{PurgeTxnLog}} utility?
> It would make sense to enable to support the {{DatadirCleanupManager}} as well.
