managin order to use epoll (tasker.network.netty.transport: epoll),
is it required that linux version is 4.0.16 or newer or not
my flink veriso is 1.4.2
my jdk version is 1.8.0.20
my linux version is:3.10.0
I try to use epoll with setting: tasker.network.netty.transport: epoll
but it throws excption which leads me here:
https://github.com/apache/flink-shaded/issues/30
I followed the instruction and still exception throws.
then I found below link Native transports whic is offical netty doc below:
http://netty.io/wiki/native-transports.html
and it says:
Netty provides the following platform specific JNI transports:
Linux (since 4.0.16)
so my question is:
in order to use this epoll, is it required that linux version is 4.0.16 or
newer or not?

Hi,
The number 4.0.16 refer to netty version, not the Linux kernel version
