> Dear,
> I created the simple pig script that reads two avro files, merges the two relations and
stores it into the output avro file.
> I tried to store output relation into avro file using:
>  store outputSet into 'avrostorage' using AvroStorage();
> Some workaround was required because pig has problems to process schema with :: (maybe
another bug?)
> Added code below the result 'avrostorage' file was generated.
> outputSet = foreach outputSet generate $0 as (name:chararray) , $1 as (customerId:chararray),
$2 as (VIN:chararray) , $3 as (Birthdate:chararray), $4 as (Mileage:chararray) ,$5 as (Fuel_Consumption:chararray);
>  
> When I tried to store avro file with the schema definition using code below,
> strange error is occurring https://bpaste.net/show/ccf0cbef06a9 (Full log).

- 1 map reduce job(s) failed!

> STORE outputSet INTO '/avro-dest/Test-20160129-1401822' 
>  USING org.apache.pig.piggybank.storage.avro.AvroStorage('no_schema_check', 'schema',
'....')

> I think these might be two important issues, could you please investigate?
> Thank you
