Daniel Templeton commented on YARN-6125:
----------------------------------------
That is certainly an option. The point that [~yufeigu] made is that if a
message is a stack trace, the most important stuff is at the top. What
[~andras.piros] is saying is that we should drop the oldest message first, but
starting from its tail, not its head. That way we
get:{noformat}java.io.IOException: Failed on local exception:
java.io.IOException: javax.security.sasl.SaslException: GSS initiate failed
[Caused by GSSException: No valid credentials provided (Mechanism level: Failed
to find any Kerberos tgt)]; Host Details : local host is:
"foo.bar.com/127.0.0.1"; destination host is: "foo.bar.com":8020;

> We've found through experience that the diagnostic message can grow
> unbounded. I've seen attempts that have diagnostic messages over 1MB. Since
> the message is stored in the state store, it's a bad idea to allow the
> message to grow unbounded. Instead, there should be a property that sets a
> maximum size on the message.
> I suspect that some of the ZK state store issues we've seen in the past were
> due to the size of the diagnostic messages and not to the size of the
> classpath, as is the current prevailing opinion.
> An open question is how best to prune the message once it grows too large.
> Should we
> # truncate the tail,
> # truncate the head,
> # truncate the middle,
> # add another property to make the behavior selectable, or
> # none of the above?
