Hi,
I got "Unknown datum type java.lang.Short" exception when I tried to encoding
data.

My schema:
{
"type": "record",
"name": "Response",
"fields":
[
{"name":"data","type":[{"type":"array","items":{"type":"array","items":["string","int","long","float","double","boolean","null"]}},"null"]}
]
}
I got data from Microsoft SQL server and one of returned fields was defined as
tinyint. I believe this tinyint field caused above exception. It seems similar
as https://issues.apache.org/jira/browse/AVRO-1500 . However, it didn't fix my
issue above. Can I define "short" in the schema?
Please advise.
Thank you,
Welly
