Load Time from HDFS

[Jack Kolokasis]

Hello,

    I want to ask if there any way to measure HDFS data loading time at 
the start of my program. I tried to add an action e.g count() after val 
data = sc.textFile() call. But I notice that my program takes more time 
to finish than before adding count call. Is there any other way to do it ?

Thanks,
