Viraj Bhat commented on PIG-3323:
---------------------------------
Hi Scott,
Thanks for your explanation for understanding default values. The
documentation on this is limited. BTW I have opened up: PIG-3331 which I think
is valid. Please let me know if it is not.
Regards

> Project: Pig
> Issue Type: Bug

> A pig script like the below succeeds, but inspecting the resulting file I
> find that the schema is stripped of the default value specification.
> {code}
> a = load ':INPATH:/types/numbers.txt' using PigStorage(':') as (intnum1000:
> int,id: int,intnum5: int,intnum100: int,intnum: int,longnum: long,floatnum:
> float,doublenum: double);
> b2 = foreach a generate id, intnum5, intnum100;
> c2 = filter b2 by 110 <= id and id < 120;
> describe c2;
> dump c2;
> store c2 into ':OUTPATH:.intermediate_2' USING
> org.apache.pig.piggybank.storage.avro.AvroStorage('
> {
> "debug" : 5,
> "schema" : {
> "name" : "schema_2",
> "type" : "record",
> "fields" : [
> {
> "name" : "id",
> "type" : [

> "type" : [
> "null",
> "int"
> ],
> "default" : 0
> }
> ]
> }
> }
> ');
> {code}
> BTW, the documentation on https://cwiki.apache.org/PIG/avrostorage.html is
> mute on the subject of defaults, so first question is: is my expectation that
> the default is to be written to file not correct?
