Subject AvroStorage issues during write into HDFS
Date Mon, 01 Feb 2016 12:46:51 GMT

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

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).

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

Sample data and pig script:


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