---------------------------------
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)
