Getting exception on storing null valued record/tupple as avro.
The input file having one column with long values (one of them is null means nothing) and when I am trying to store the data in avro format ,it throws error.
Please suggest if I am missing any thing some where as per the bellow codebase or else please provide the patch.
******My code base.
REGISTER /home/hadoop/work/sudhir/AvroAnalysis/Avrojars/snappy-java-1.0.4.1.jar

– The input file only have 1 column (normal TEXT data i.e TSV format) and the file having a null value means nothing
A = load '/home/hadoop/work/sudhir/AvroAnalysis/input/TSV_uncompressed/part*' using PigStorage('\t') as (USER_ID:long);
– The soutput to be stored in avro data format
STORE A INTO '/home/hadoop/work/sudhir/AvroAnalysis/output/TSV_uncompressed/part*' USING org.apache.pig.piggybank.storage.avro.AvroStorage('schema','{"namespace":"com.sudhir.schema.users.avro","type":"long","name":"users_avro","doc":"Avro storing with schema using Pig.","fields":[
]}');
