I've set up small cluster for the education and training purposes and after the weekend I see that all disks are 100% full. The cluster was only set up with no data loaded. It seems, that monitoring streams ate all the space. I tried to change TTL, but received alterTable error 28 - Disk is full. When I try to purge the volume as mapr user, it does not do anything and all the disks are still 100% full ... any advice?
