Jacques Nadeau commented on DRILL-4325:
---------------------------------------
[~vicky], would you be willing to run your same oversaturation test and see if
our stability is better with this simple patch?
https://github.com/jacques-n/drill/tree/DRILL-4466b
I'd like to see if we can help the kernel scheduler enough that it runs work at
a larger quantum. This won't solve the gross over-parallelization issue
directly but it may help the system context switch less.
In reality, a change in scheduling won't actually impact the core problem of
too many simultaneous tasks. No matter the threading model, having 4000 tasks
competing for ~40 logical cores is going to mean slow progress. Clearly we need
to increase the switch quantum in these cases so we make forward progress
(hopefully impacted with my small patch). However, if we target a quantum of
100ms, that means tasks would wait 10s between each 100ms of work. In other
words, we can't schedule this many tasks and expect speedy forward progress. We
need to enable inbound controls as well as ensure that we reduce the
parallelization behavior on a heavily loaded node.

> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Flow
> Affects Versions: 1.5.0
> Reporter: Victoria Markman
> Attachments: drillbit.log.133, drillbit.log.134, drillbit.log.135,
> drillbit.log.136, stats.133.tar, stats.134.tar, stats.135.tar, stats.136.tar,

>
> The picture pretty much looks like this: bunch of queries are running
> (usually something more involved than just simple functional tests),usually
> tpch or tpcds with lots of major fragments, like query74 from tpcds .
> Zookeeper decides that particular node is dead and queries that were running
> at the time of the connection loss are failed by drill ( which is correct
> behavior, I think )
> It seems that I can reliably reproduce this issue when I bump up number of
> concurrently running queries and make all of them go to the same forman node
> (I don't really imply here that planning is to blame, just seems to
> reproduce easier)
> On my 4 node cluster I can pretty much reproduce this problem relaiably by
> running:
> run.sh -s Advanced/tpcds/tpcds_sf100/original -g smoke -t 600 -n 10
