Michael Stack commented on HBASE-24126:
---------------------------------------
Ok. Finally figured how to up the nproc limit after pushing 4 times -- an
original and 3 three addendums -- against this issue on branch-2.
In short, we pass an arg. when we do 'docker run' to up ulimit for nproc on the
container and then once the container is running, we pass an upped proclimit to
yetus so it will use the new max.
Made a PR for master that is an aggregate of the four pushes.
> Up the container nproc uplimit from 10000 to 12500

> Let me up the container nproc count from 10000. If many tests running in
> parallel, container could breach the 10000 limit: i.e. if a bunch of
> heavy-duty long tests run at same time (0.5C on a 16CPU machine means 8
> possible concurrents) and we spin up 1-2000 threads in each test, then could
> hit the 10000 limit. Move up the limit some expecially after INFRA just upped
> our limit to 30000.
