Hi MJ.
This is a bug, i've created a jira for it:
https://issues.apache.org/jira/browse/IGNITE-15867
However this should not affect ignite workflow, since it just produces
excessive stack traces and nothing more.

(line:4227) vs 2.10.0 , the method( public static void
close(@Nullable Socket sock, @Nullable IgniteLogger log) ) is newly
added. Not sure if these methods close/closeQuiet ’s related to
IGNITE_QUIET setting but it’s always throwing below warnings no matter
IGNITE_QUIET is true or false .

ERROR. I am not sure if that’s the issue in my code or just flaw in
ignite. But is there any other way to gracefully clean up them by coding
? Those exception stacktraces are not good for production usage.
