    Description

      The current default config for "taskmanager.net.transport" in NettyShuffleEnvironmentOptions is "NIO". In order to use "EPOLL" mode which has better performance and is recommended when available, we could change the default config as "AUTO". Then the "NIO" mode is used as a fallback.
