    Description

      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 !!!
