------------------------------------
[~dawidwys]Thanks for reply, I dont see any async commit failed message, whole
list of log will look like below, I also update to flink 1.7.0 and kafka
consumer to latest, still got the same problem.
```
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-connector-kafka_2.11</artifactId>
<version>1.7.0</version>
</dependency>
```
The warning about `MultipartUploadOutputStream` is quite ambigous
All log here:
Right after deploy the app:
