Eddy ALBERT updated AVRO-2101:
------------------------------
Description:
Hi,
It seems there is a bug in the Avro library when generating the Avro source
files from the Avro schema.
As you could see in appendice, my schema is based on a main record and several
sub-records.
I work with "unions" for the type definition to allow setting fields to null
when the value is not present.
*The issue is the following*:
First of all, this behavior isn't deterministic!
When the library generates the source file, most of the sub-records are well
generated (with null as the default value), but sometime, a single sub-record
has its default value set to "null" (String).
If I change the default value of the issued sub-record to "foo" and I
re-generate the source file, I can see "foo" as the default value. If I
rollback that change (back the default value to null) and I re-generate, I
finally get null as default value (but not everytime ...).
I think this issue is the source bug of the one I publish on Stackoverflow:
[https://stackoverflow.com/questions/46775649/handle-nested-avro-record-when-the-one-is-null/46786313#46786313]
Any suggestions?
Best regards,
EddyA.
Ps: its is always the same sub-record that is issued (mobile_web_event).

{
"name": "url",
"type": ["null", "string"],
"default": null
},
{
"name": "user_agent",
"type": ["null", "string"],
