A jar upload shouldn't take minutes. There are two possibilities that likely 
co-occured:
- your jar is much bigger than needed. Did you make sure that you don't put 
Flink into the fatjar? That's counterproductive on many levels. Please check 
the jar size.

- your connection to the JM is bad. Where is your Flink cluster running? If 
connection is superslow, it's often better to build the jar on the respective 
server and submit on command line or through REST.

Hello my friend:
    My line of code runs very slowly. What are the possibilities?
 code:
CompletableFuture<JobGraph> jarUploadFuture = 
jobGraphFuture.thenCombine(blobServerPortFuture, (jobGraph, blobServerPort) -> {
  final InetSocketAddress address = new 
InetSocketAddress(gateway.getHostname(), blobServerPort);
   try {
      ClientUtils.extractAndUploadJobGraphFiles(jobGraph, () -> new 
BlobClient(address, configuration));
   } catch (FlinkException e) {
      throw new CompletionException(e);
   }
   return jobGraph;
});
