Guillaume Vauvert commented on FLINK-25732: ------------------------------------------- This issue is impacting all deployments with 2 JobManagers or more (HA mode), because in this case serialization is used (well, depending on the JobManager who is responding, the Leader or a Follower). It prevents: * usage of Flink UI * usage of Flink command "flink.sh list" * usage of Flink REST API "/jobs/overview" > Dispatcher#requestMultipleJobDetails returns non-serialiable collection > ----------------------------------------------------------------------- > > Key: FLINK-25732 > URL: https://issues.apache.org/jira/browse/FLINK-25732 > Project: Flink > Issue Type: Bug > Components: Runtime / Coordination > Affects Versions: 1.15.0, 1.13.6, 1.14.3 > Reporter: Chesnay Schepler > Assignee: Chesnay Schepler > Priority: Major > Labels: pull-request-available > Fix For: 1.15.0, 1.13.6, 1.14.4 > > > HashMap#values() returns a non-serializable collection. -- This message was sent by Atlassian Jira (v8.20.1#820001)
