[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=16967103#comment-16967103 ] 

David Judd commented on FLINK-13417:
------------------------------------

Flagging interest in this because ZK 3.5 also contains a fix for https://issues.apache.org/jira/browse/ZOOKEEPER-1576 - which we're running into & has the effect that (since we provide hostnames instead of IPs currently) the inability to reach a single Zookeeper host from the Flink job manager will bring it, and therefore the Flink cluster, down.

> 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.
