Major Description
Currently, YCSB smoke test runs ycsb with the -s option, which outputs processing status to a file, and its size can be over 500MB.
It's not so huge for general environments, but our CI servers for x86_64 have only 8GB as a root volume.
They store test results under /home/jenkins/workspaces on the root volume for each distro, so the total size can be 3GB+. It easily runs short of their disk.
I'm planning to extend their root volume in the near future, but I'd like to suppress the output as a workaround for now.
