Hi, 1 - I installed Hadoop MRv2 in VirtualMachines. When the jobs are running, I try to list them with "hadoop jobs -list", but it takes lots of time for the command being executed. This happens because of the performance of the VM. I just wonder how it works with big machines. Does anyone have an idea if it takes long to launch Hadoop commands while executing jobs?
2 - I want to run several jobs at the same time. How can I configure the maximum number of jobs that I can run at the same time? 3 - Is there a calculation of how many jobs I can run at the same time for specific environment similar to how many reduces should we set in our jobs? Thanks, -- Best regards,
