Subject [jira] [Commented] (CRUNCH-52) Writing to a text file with avro types fills a file with the tostring of AvroWrapper
Date Tue, 28 Aug 2012 10:59:07 GMT

    [ https://issues.apache.org/jira/browse/CRUNCH-52?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13443061#comment-13443061

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 ?
