Fetch failures can take way too long for a map to be restarted

      Description

      In one particular case we saw a NM go down at just the right time, that most of the reducers got the output of the map tasks, but not all of them.

      The ones that failed to get the output reported to the AM rather quickly that they could not fetch from the NM, but because the other reducers were still running the AM would not relaunch the map task because there weren't more than 50% of the running reducers that had reported fetch failures. Then because of the exponential back-off for fetches on the reducers it took until 1 hour 45 min for the reduce tasks to hit another 10 fetch failures and report in again. At that point the other reducers had finished and the job relaunched the map task. If the reducers had still been running at 1:45 I have no idea how long it would have taken for each of the tasks to get to 30 fetch failures.

      We need to trigger the map based off of percentage of reducers shuffling, not percentage of reducers running, we also need to have a maximum limit of the back off, so that we don't ever have the reducer waiting for days to try and fetch map output.

        OK so I missed some of the code in shuffleScheduler.checkReducerHealth(). The stall check is in there, but the previous check for a single map attempt is completely useless at this point. Dropping the severity accordingly.

        I am also confused why a reducer could be stalled for over an hour (MAPREDUCE-4772) and not be killed. I will look into that here too.

        Boy I feel dumb, I commented on the wrong JIRA and reduced its priority. The above two comments were for MAPREDUCE-4775. Moving this one back to critical.

        This patch changes the AM to restart a map task if 50% of the shuffling reducers report errors for a given map task instead of 50% of the running reducers.

        It also changes how often a reduce reports fetch failures. If a ConnectionException happens then it will report the error immediately and will not wait. A ConnectionException indicates that there is no one listening on the remote port. This is very different from a timeout where the port is overrun and no one is able to get through.

        It also adds in a maximum delay between fetch retries. In the original code every time a fetch failure happened the reducer would add 30% to the delay. It would also only report every 10th failure. This means that the first failure would be reported after about 6 min, the second after 90 min and the third after 20 hours. This is really bad when there is only one reducer because the AM requires at least three reports for the map task to be restarted.

        The default maximum delay is set to 1 min which would change the numbers to be 6 min, 15 min, and 25 min respectively. 25 min still seems very long to wait, but is much better then 20 hours.

        Oh the only differences between 0.23 and trunk is that 0.23 includes one extra include in JobImpl that was not needed by trunk.

        Changes are looking good. I agree with the fact that there is no way to configure infinite fetch failure backoff anymore as part of this JIRA. Is there anything that can be changed to remove the javac warnings here?

        OK So all of the javac warnings relate to the fact that the event dispatcher is a generic but is not really fully typed. I could put in @IgnoreWarning, but that just masks the known problem. Sorry I don't really see any way without some serious changes to the event dispatcher API.
