Subject [GitHub] spark issue #14961: [SPARK-17379] [BUILD] Upgrade netty-all to 4.0.41 final ...
Date Tue, 13 Sep 2016 12:43:07 GMT
Github user a-roberts commented on the issue:
    [info] - using external shuffle service *** FAILED *** (1 minute)
    [info]   java.util.concurrent.TimeoutException: Can't find 2 executors before 60000 milliseconds
    60 seconds really is an eternity, I can't reproduce this on my local set up, I expect
we've got deadlock going on after the upgrade and would require some proper debugging (again,
if only I could reproduce it on my test systems with access to tools like gdb/healthcenter/servicing
APIs we use here). My systems have between two and eight cores and I know this farm has a
lot more available...could be that having more cores increases the chances of thread contention.
    I had a look at other pull requests being tested and see it typically completes in 3 seconds
on a good run
    using external shuffle service (3 seconds, 822 milliseconds)
    using external shuffle service (4 seconds, 543 milliseconds)
