> Hi All,
> it is possible make fair scheduler pools pluggable? so that we can
> implement our own SchedulingAlgorithm. In our case, we want to limit the
> max tasks number of one job which will load data from mysql database, if we
> set a bigger executer.number * cores.number, it will trigger alarm. Or we
> can do this in an other way?
