> I found that the Hybrid Shuffle without enabling new mode may hang when exclusive-buffers-per-channel is set to 0. It can be reproduced by adding the following test into `HybridShuffleITCase.java` and running it.
> {code:java}
> @RepeatedTest(10)
> void testHybridFullExchangesWithNonBuffersPerChannel() throws Exception {
>     final int numRecordsToSend = 10000;
>     Configuration configuration = configureHybridOptions(getConfiguration(), false);
>     configuration.set(
>             NettyShuffleEnvironmentOptions.NETWORK_HYBRID_SHUFFLE_ENABLE_NEW_MODE, false);
>     configuration.set(NETWORK_BUFFERS_PER_CHANNEL, 0);
>     JobGraph jobGraph = createJobGraph(numRecordsToSend, false, configuration);
>     executeJob(jobGraph, configuration, numRecordsToSend);
> } {code}
