Ferenc Csaky commented on FLINK-36533:
--------------------------------------

We hit the same issue described in SPARK-18383. In case of "epoll" Netty transport (which is a Linux-only feature), Netty uses different sockets and throws a different exception type in case of a used address. Will raise a PR shortly.
