Yang Wang commented on FLINK-27099:
-----------------------------------
After the job is submitted successfully, the uploaded jars which are located in
the /tmp directory could be deleted via {{{}DELETE /jars/:jarid{}}}.
However, the problem is the deleted files are still occupying disk space. You
could verify this by 'lsof | grep deleted'.

> Key: FLINK-27099
> URL: https://issues.apache.org/jira/browse/FLINK-27099
> Project: Flink
> Issue Type: Bug
> Components: Runtime / REST
> Affects Versions: 1.7.2, 1.12.1, 1.14.4
> Reporter: Mexicapita
> Priority: Minor
>
> I have some problems with my apache flink stream system.
> A few days ago, we detect that flink was using too much space in the hard
> disk, and explorint them, we found to many (around a thousand) `.jar` files
> in `/tmp` directory on jobmanager container.
> The .jar files always have a similar name, but with diferent numbers:
> - 1695477181_3183563526079495551lib_org.eclipse.paho.client.mqttv3-1.1.0.jar
> - 1798263280_2346102789822957064lib_com.google.protobuf_2.6.0.jar
> The .jar files was created when I use the 'Submit New Job' menu
> In this menu, flink start to polling `GET http://myflink:myport/jars/` (once
> at second).
> For each request, a couple of .jar files are created.
> I can't find any information about this and I'm not sure if its a bug or
> something. Any help please ?
> My installations:
> - Flink 1.12.1 running with docker swarm
> - Flink 1.7 running with docker compose
> - Flink 1.14.4 java 11 running with docker-compose
> The three installations have the same problem
> Thanks !!!
