we are using hive1.1 .
I was able to fix below error when I used right version spark
15/08/26 17:51:12 WARN avro.AvroSerdeUtils: Encountered AvroSerdeException
determining schema. Returning signal schema to indicate problem

But I still see this error when querying on some hive avro tables.
15/08/26 17:51:27 WARN scheduler.TaskSetManager: Lost task 30.0 in stage

I haven't tried spark-avro. We are using Sqlcontext to run queries in our
application
Any idea if this issue might be coz of querying across different schema
version of data ?
Thanks
