I've build an Apache Flink app and packaged it in a fat JAR with Gradle Shadow Plugin. The resulting file size is ~114 MiB. When I'm trying to upload it with Flink's web UI it is stuck in "Saving…" phase. And if I use curl to upload it manually the result is "413 Request Entity Too Large":
$ curl -X POST -H "Expect:" -i -F "[email protected]" http://ec2-18-204-247-166.compute-1.amazonaws.com:8081/jars/upload
HTTP/1.1 413 Request Entity Too Large
content-length: 0
What are the options, then?
UPD: I can see the JAR in /tmp/flink-web-UUID/flink-web-upload/UUID/flink-all.jar but it is not recognized by Flink (not visible on UI).
Ok, it was easy to fix.
First, I've scanned their repo for "Too Large" string and found this class. Looks like SERVER_MAX_CONTENT_LENGTH is responsible for max object size. It is set here from the configuration option rest.server.max-content-length. The default is 100 MiB.
TLDR:
Setting rest.server.max-content-length in flink-conf.yaml to 209715200 (200 MiB) solved the issue.
