[jira] [Created] (FLINK-20643) flink-connector-elasticsearch7
causes Direct buffer memory OOM
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:
