Sorry for the stupid question, I am new to scala. When I execute following simple hadoop commands within zeppelin scala interpreter panel, I don't get any outputs except res120: Int = 0 is this normal? what would be the best way to parse hdfs from zeppelin?
import sys.process._ "hadoop fs -ls /user/hdfs/files" ! import sys.process._ warning: there were 1 feature warning(s); re-run with -feature for details res120: Int = 0
