I am practicing on AWS instance for HDPCD test. I have taken m3.xlarge instance. Hadoop services are not started by default. I just executed start-all-services.sh. It is taking very long time. I waited for more than 15 mins. It is still going on. Is the speed of m3.xlarge instance enough? Or should I go for higher? Response on the terminal is fine.
