[jira] [Created] (FLINK-10177) Use transport type AUTO by default

Nico Kruber created FLINK-10177:
-----------------------------------

             Summary: Use transport type AUTO by default
                 Key: FLINK-10177
                 URL: https://issues.apache.org/jira/browse/FLINK-10177
             Project: Flink
          Issue Type: Improvement
          Components: Configuration, Network
    Affects Versions: 1.6.0, 1.7.0
            Reporter: Nico Kruber


Now that the shading issue with the native library is fixed (FLINK-9463), EPOLL should be available on (all?) Linux distributions and provide some efficiency gain (if enabled). Therefore, {{taskmanager.network.netty.transport}} should be set to {{auto}} by default. If EPOLL is not available, it will automatically fall back to NIO which currently is the default.
