[Shang Yuanchun (Jira)]

Echo Lee created FLINK-20643:
--------------------------------

             Summary: flink-connector-elasticsearch7 causes Direct buffer memory OOM
                 Key: FLINK-20643
                 URL: https://issues.apache.org/jira/browse/FLINK-20643
             Project: Flink
          Issue Type: Bug
          Components: Connectors / ElasticSearch
    Affects Versions: 1.11.1
            Reporter: Echo Lee
             Fix For: 1.13.0


flink version: 1.11.1

elasticsearch version: 6.3.1

jdk version: 1.8.0_152

deployment mode: Standalone

My job run normally under flink-connector-elasticsearch6, but failed under flink-connector-elasticsearch7. It can be solved by increasing the *taskmanager.memory.framework.off-heap.size* or *taskmanager.memory.task.off-heap.size* parameter, but I don't quite understand why it costs more off-heap memory on es7 than on es6.

error message is:
