Vinod Kumar Vavilapalli commented on YARN-292:
----------------------------------------------
Thanks for the logs Nemon.
Looked at the logs. We were so focused in removals that we forgot the puts. And
as the logs clearly pointed out, another app was getting added at (almost) the
same point of time as get, and since this is a TreeMap (or even HashMap), there
are structural changes even with a put :)
The ptach isn't applying anymore, can you please update?
Also can you try to write a simple test, with one threads putting lots of apps
and the other trying to allocate the AM? Not a very useful test, but can give
us a little confidence.
