Description

When creating an Avro IDL file, if the developer adds multiple enumerations and/or records with the same name, no error or warning is shown when generating the AVSC file via the avro-tools idl2schemata operation. For example, given the following AVDL file...

@namespace("yournamespace") 
protocol ExampleSchema
{ 
   enum typeCode{AA,BB,CC,DD} 
   enum typeCode{ZZ,YY,XX,VV}   
   record name{ typeCode typeCode; } 
   record address{ typeCode typeCode; } 
   record address{ string someName; } 
   record message{ address address; name name; } 
}

...the generated AVSC will show (I'm having some trouble with the formatting here so I'll include an image and the text):

 

 

{  "type" : "record",  
"name" : "message",  
"namespace" : "yournamespace",  
"fields" : [ {    
"name" : "address",    
"type" : {      "type" : "record",      "name" : "address",      "fields" : [ {        "name" : "someName",        "type" : "string"      } ]    }  }, {    "name" : "name",    "type" : {      "type" : "record",      "name" : "name",      "fields" : [ {        "name" : "typeCode",        "type" : {          "type" : "enum",          "name" : "typeCode",          "symbols" : [ "ZZ", "YY", "XX", "VV" ]        }      } ]    }  } ]}
 

Here, the first enumeration is ignored, as is the first definition of address, as provided in the AVDL file.
