Chesnay Schepler created FLINK-22224:
----------------------------------------

             Summary: Nettys NativeLibraryLoader is quite noisy
                 Key: FLINK-22224
                 URL: https://issues.apache.org/jira/browse/FLINK-22224
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Network
            Reporter: Chesnay Schepler


These errors are logged on debug, with excessive stack traces, and it is unclear whether this is a problem or not:
{code}
DEBUG org.apache.flink.shaded.netty4.io.netty.util.internal.NativeLibraryLoader [] - Unable to load the library 'org_apache_flink_shaded_netty4_netty_transport_native_epoll_x86_64'
DEBUG org.apache.flink.shaded.netty4.io.netty.util.internal.NativeLibraryLoader [] - org_apache_flink_shaded_netty4_netty_transport_native_epoll_x86_64
{code}
But immediately afterwards this show up:
{code}
NativeLibraryLoader [] - Successfully loaded the library /tmp/liborg_apache_flink_shaded_netty4_netty_transport_native_epoll_x86_64670877569787969381.so
{code}
