Github user zentol commented on the issue: https://github.com/apache/flink/pull/4654 This doesn't solve the problem of the JIRA. For the job submission we have to send jars to the cluster, which may be multiple 100mb large; we obviously can't allocate that much memory in general. As @kl0u said, setting this value any higher (it is already _very_ high) will cause insane memory consumption in the object aggregator in any case where concurrent requests are in progress. As such this isn't even a temporary fix, as this is not a viable fix for the use-cases that are affected by the limit, so I'm afraid we'll have to reject this PR.
