---------------------------------

             Summary: Pipeline.writeTextFile should work with Avro data
                 Key: CRUNCH-147
                 URL: https://issues.apache.org/jira/browse/CRUNCH-147
             Project: Crunch
          Issue Type: Improvement
          Components: Core
    Affects Versions: 0.4.0
            Reporter: Dave Beech
            Assignee: Josh Wills
            Priority: Minor


I'd find it useful to be able to dump Avro collections to a text file (as json) during development to have a quick look inside without having to mess around with avro-tools. The current Pipeline.writeTextFile method expects Writables and gives the following error when you attempt to pass Avro to it:

Exception in thread "main" java.lang.ClassCastException: class my.avro.Record
	at java.lang.Class.asSubclass(Class.java:3018)
	at org.apache.crunch.types.writable.Writables.records(Writables.java:250)
	at org.apache.crunch.types.writable.WritableTypeFamily.records(WritableTypeFamily.java:86)
	at org.apache.crunch.types.PTypeUtils.convert(PTypeUtils.java:61)
	at org.apache.crunch.types.writable.WritableTypeFamily.as(WritableTypeFamily.java:135)
