Data locality

Hi All,

I developed a scheduler for data locality. Now I want to test the performance of the scheduler, so I need to monitor how many data are read remotely. Is there any tool for monitoring the volume of data moved around the cluster?

Thanks,
Fei

hi, folks,

I have the similar question. Is there an easy way to tell(from a user
perspective) whether short circuit is enabled? thanks
