---------------------------------
Attachment: simpleTest.zip
Sample avsc files
> avrogen.exe "import" handling
> -----------------------------
>
> Key: AVRO-1724
> URL: https://issues.apache.org/jira/browse/AVRO-1724
> Project: Avro
> Issue Type: Bug
> Reporter: Norman Fung JP
> Attachments: simpleTest.zip
>
>
> I have two simple JSON Schema in SAMEfolder:
> Content in "simpleA.avsc" as follows:
> {
> "namespace": "com.bearstearns",
> "type": "record",
> "name": "simpleA",
> "imports": ["simpleB.avsc"],
> "fields":
> [
> {"name":"appName","type":"string"},
> {"name":"userId","type":"string"},
>
> {"name":"nestedB","type":[{"type":"array","items":"simpleB"},"null"]}
> ]
> }
> Content in "simpleB.avsc" as follows:
> {"namespace": "com.bearstearns",
> "type": "record",
> "name": "simpleB",
> "fields":
> [
> {"name":"ID","type":"string"},
> {"name":"SimpleName","type":"string"}
> ]
> }
> Avrogen can be downloaded from Download from
> http://apache.communilink.net/avro/avro-1.7.7/avro-csharp-1.7.7.tar.gz
> From Command Prompt,
> avrogen -s simpleA.avsc outputDir
> The error message is:
> "Exception occurred. Undefined name: simpleB"
> I also try using avrogen -p switch in combination with protocol file, no joy.
> For this method, I first define the protocol file "bearstearns.avdl"
> @namespace("com.bearstearns")
> protocol BearStearns {
> import schema "simpleA.avsc";
> import schema "simpleB.avsc";
> }
> Then from command prompt:
> avrogen -p bearstearns.avdl outputDir
> This time, the error message is,
> Exception occurred. Invalid JSON format: @namespace("com.bearstearns")
> protocol BearStearns {
> import schema "simpleA.avsc";
> import schema "simpleB.avsc";
> }
> Actually is Avro support for dotnet ready yet? Avro official doc for C# is
> completely empty: http://avro.apache.org/docs/current/api/csharp/index.html
> Their guys even created a ticket for this in DEC 2013.
> https://issues.apache.org/jira/browse/AVRO-1420
> As of August 2015, Avro doc for C# remains empty. And not much foot print in
> Internet (C# and Avro I meant).
