Aljoscha Krettek commented on FLINK-7300:
-----------------------------------------
The reason this time is an {{AskTimeoutException}}. The problem is that even a
normal run of Flink can have exceptions and errors in the log. In our release
testing we have this section about "running a cluster and verifying that the
log and output are clear of exceptions and errors". I think in the real world
the log is never clear of exceptions and errors, even in the case where
everything wen't well.
[~till.rohrmann] You think we should maybe just not test for the log being
clean? I could also add {{AskTimeoutException}} to the list of exceptions that
we expect to occur. I'm guessing this just sometimes occurs with Akka?
