title: uncompress and read gzip file in scala
body: <p>In Scala, how does one uncompress the text contained in <code>file.gz</code> so that it can be processed? I would be happy with either having the contents of the file stored in a variable, or saving it as a local file so that it can be read in by the program after.</p>
  
  <p>Specifically, I am using Scalding to process compressed log data, but Scalding does not define a way to read them in <code>FileSource.scala</code>.</p>
