sarath updated PIG-4943:
------------------------
Description:
I have a script which stores 2 relations with different schema using
CSVExcelStorage.
The issue which i see is that the script picks up the last store function and
takes the schema in that and puts it for all store functions , overriding the
previous store schemas.Is this a known issue and is there a fix for this ?
My Sample Script Looks like this :--
=============================================================
masterInput = load 'hbase://xyz' using
org.apache.pig.backend.hadoop.hbase.HBaseStorage(
'f:a,f:b,f:c,f:d')
as (a,b,c,d);
input2 = foreach masterInput
generate
a,b;
input3 = foreach masterInput
generate
c,d;
store input2 into '/dir/ab'
using org.apache.pig.piggybank.storage.CSVExcelStorage('\t','YES_MULTILINE',
'UNIX', 'WRITE_OUTPUT_HEADER');
store input3 into '/dir/cd'
using org.apache.pig.piggybank.storage.CSVExcelStorage('\t','YES_MULTILINE',
'UNIX', 'WRITE_OUTPUT_HEADER');
=============================================================
Expected Output :
||file 1||file1||file 2||file2
|a|b|c|d
|10|20|30|40
Actual Output :
||file 1||file1||file 2||file2
|c|d|c|d
|10|20|30|40
