Hello all,

I’m having an issue using AvroMultipleOutputs in a map/reduce job.  The issue 
occurs when using a schema that has a union of null and a fixed (among other 
complex types), default to null, and it is not null.  Please find the full 
stack trace below and a sample map/reduce job that generates an Avro container 
file and uses that for the m/r input.  Note that I can serialize/deserialize 
without issue using GenericDatumWriter/GenericDatumReader outside of hadoop…  
Any insight would be helpful.

2014-03-04 Thread Stanley Shi 
Which version of hadoop are you using?
There's a possibility that the hadoop environment already have a avro**.jar
in place, thus caused the jar conflict.
