Rahul Sharma commented on CRUNCH-52:
------------------------------------
Some addition to this, when we try to write avro data to text using
pipeline.writeToTextFile(.....) it throws back ClassCastException as the class
is not of type o.a.hadoop.io.Writable
java.lang.ClassCastException: class org.apache.crunch.test.Person
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)
So should it be allowed to write back avro data to text files ? If so,
shouldn't the behavior be the same at both the places ?
> Writing to a text file with avro types fills a file with the tostring of
> AvroWrapper
