This script loops through hdfs files system and reads the first line and writes it to console.  Most part its self explanatory.

This script uses pipeline delimiter  “|” .  Its optional and can be skipped.

import org.apache.hadoop.fs.Path

import org.apache.hadoop.conf.Configuration
import org.apache.hadoop.fs.FileSystem
val path = "/hdfspath/"
val conf = new Configuration()
val fs = FileSystem.get(conf)
val p = new Path(path)
val ls = fs.listStatus(p)
ls.foreach( x => {
val f = x.getPath.toString
val content ="delimiter","|").csv(f)
} )
