Generating Avro files for unit tests
meghana narasimhan 2013-01-26, 03:33
Hi All,

I am trying to generate input files using Java. I have raw data in a CSV
file, which Java reads and then uses GenericDatum/Record to create Avro
files. The avro file is valid as it is parsed properly by avrocat.

 But, I get this error when I try to load it in Pig grunt :

DEFINE AVRO_STORAGE org.apache.pig.piggybank.storage.avro.AvroStorage();

logdata = LOAD
'/Users/xxxx/Documents/workspace/DP-1147/apache-traffic-export/target/test-classes/output.avro'
USING AVRO_STORAGE();

2013-01-25 16:25:06,067 [main] ERROR org.apache.pig.tools.grunt.Grunt -
ERROR 1200: Pig script failed to parse:
<line 4, column 10> pig script failed to validate:
java.lang.RuntimeException: could not instantiate
'org.apache.pig.piggybank.storage.avro.AvroStorage' with arguments 'null'
Details at logfile: /Users/xxxx/pig_1359157245908.log
What should I be using instead?
