hey guys I am using spark 1.0.0+cdh5.1.0+41 When two users try to run "spark-shell" , the first guy's spark-shell shows active in the 18080 Web UI but the second user shows WAITING and the shell has a bunch of errors but does go the spark-shell and "sc.master" seems to point to the correct master.
I tried controlling the number of cores in the "spark-shell" command --executor-cores 8 Does not work thanks sanjay
