I am not sure, I haven't tested it using scala.
com.hadoop.mapreduce.LzoTextInputFormat class is from this package
https://github.com/twitter/hadoop-lzo
I have installed it from clourdera "hadoop-lzo" package with liblzo2-2
debian package on all of my workers. Make sure you have hadoop-lzo.jar
in your class path for spark.
