*Hi,*

*I am trying to read csv data and write as avro data,*

REGISTER /usr/lib/pig/lib/avro-1.7.4.jar;
REGISTER /usr/lib/pig/lib/piggybank.jar;
REGISTER /usr/lib/pig/lib/jackson-mapper-asl-1.8.8.jar;
REGISTER /usr/lib/pig/lib/jackson-core-asl-1.8.8.jar;
REGISTER /usr/lib/pig/lib/json-simple-1.1.1.jar;

A = LOAD '/data/raw/event';

store A into '/data/dev/raw/pig'

using org.apache.pig.piggybank.storage.avro.AvroStorage('no_schema_check',
'schema', ' {
"name" : "EVENT",
"type" : "record",
"fields" : [ {
"name" : "evt",
"type" : [ "long", "null" ]
}, {
"name" : "mac",
"type" : [ "int", "null" ]
}, {
"name" : "sec",
"type" : [ "int", "null" ]
} ]

}');
