When I start a spark-shell from machine B to spark master on B I get this:

scala> sc.master
res3: String = spark://machinB:7077

scala> sc.textFile("/tmp/data/myfile.csv").count()
res4: Long = 976

But when I start a spark-shell from machine A, pointing to spark master on B I get this:

scala> sc.master
res2: String = spark://machineB:7077

scala> sc.textFile("/tmp/data/myfile.csv").count()
