[jira] [Commented] (FLINK-13417) Bump Zookeeper to 3.5.5

    [ https://issues.apache.org/jira/browse/FLINK-13417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16892464#comment-16892464 ] 

TisonKun commented on FLINK-13417:
----------------------------------

Nice proposal [~knaufk]! IIRC several runtime issues could be solved with zookeeper CONTAINER znode mode that introduced in 3.5.x

ZooKeeper has just released the production ready version 3.5.5 so I generally vote for this issue.

Keep in mind that it would(in fact, I think it must) cause some subtle issues so it should be fully tested.

cc [~till.rohrmann], I would try to link those runtime issues later.

> This requires a Zookeeper version >= 3.5.1. We might as well try to bump it to 3.5.5, which is the latest version.
