MultiStorage in pig

问题

I have run the below pig script in the grunt shell

Register D:\Pig\contrib\piggybank\java\piggybank.jar;

a = load '/part' using PigStorage(',') as (uuid:chararray,timestamp:chararray,Name:chararray,EmailID:chararray,CompanyName:chararray,Location:chararray);

store a  into '/output/multistorage' USING MultiStorage('/output/multistorage','2', 'none', ',');

while running this it throws error as shown below

2015-11-03 05:47:36,328 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 10
70: Could not resolve MultiStorage using imports: [, java.lang., org.apache.pig.
builtin., org.apache.pig.impl.builtin.]

Can any one help me in this?

You did not import your function as the log claims. If the jar is actually accessible for you, you can try the following code (There was one missing line):

REGISTER D:\Pig\contrib\piggybank\java\piggybank.jar; 
DEFINE MULTISTORAGE org.apache.pig.piggybank.storage.MultiStorage(); 
a = LOAD'/part' USING PigStorage(',') AS (uuid:chararray,timestamp:chararray,Name:chararray,EmailID:chararray,CompanyName:chararray,Location:chararray); 
STORE a  into '/output/multistorage' USING MULTISTORAGE('/output/multistorage','2', 'none', ',');

You are then partitionnig by Name.
