[jira] [Comment Edited] (FLINK-18733) Jobmanager cannot start in HA
mode with Zookeeper
[ https://issues.apache.org/jira/browse/FLINK-18733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17165756#comment-17165756 ]

-----------------------------------------------------------------
Thanks for reporting this issue [~lilyevsky]. Could you share with us the cluster logs for further debugging? It would also be helpful to better understand in which environment you are deploying Flink. We bumped the ZooKeeper version from {{3.4.10}} to {{3.4.14}} for the {{1.11.0}} release (FLINK-18042 & FLINK-16955). This change might be causing the problems you are observing.
