Helmut Zechmann created FLINK-10150:
---------------------------------------
Summary: Inconsistent number of "Records received" / "Records sent"
Key: FLINK-10150
URL: https://issues.apache.org/jira/browse/FLINK-10150
Project: Flink
Issue Type: Bug
Components: Webfrontend
Affects Versions: 1.6.0, 1.5.2, 1.4.0
Reporter: Helmut Zechmann
Attachments: record_counts_flink_1_3.png, record_counts_flink_1_4.png
The flink web ui displays an inconsistent number of "Records received" /
"Records sent” in the job overview "Subtasks" view.
When I run the example wordcount batch job with a small input file on flink
1.3.2 I get
* 3 records sent by the first subtask and
* 3 records received by the second subtask
This is the result I would expect.
If I run the same job on flink 1.4.0 / 1.5.2 / 1.6.0 I get
* 13 records sent by the first subtask and
* 3 records received by the second subtask
In real life jobs the numbers are much more strange.
