Norman Fung JP updated AVRO-1724:
---------------------------------
Description:
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
http://apache.communilink.net/avro/avro-1.7.7/avro-csharp-1.7.7.tar.gz
After download, from command prompt set PATH environment variable:
set PATH=%PATH%;C:\...\avro\codegen\Release
>From Command Prompt,
avrogen -s simpleA.avsc outputDir
The error message is:
"Exception occurred. Undefined name: simpleB"
By the way, you cannot get around this by putting two schema in one file: Only
one on top will be generated. The one in bottom won't.
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).
