Facing issue while using avro-maven-plugin
Hi,
I have created below .avsc schema file and I tried creating corresponding
classes by using avro tool and with plugin, but there are few errors on
generated java code. What could be the issue?
{"namespace": "test.avro",
"type": "record",
"name": "Session",
"fields": [
{"name":"VisitCommon", "type": {
"type": "map", "values":"string"}},
{"name":"events",
"type": {
"type": "array",
"items":{
"name":"Event",
"type":"map",
"values":"string"}
}
}
]
}
1) Error: The method deepCopy(Schema, List<Map<CharSequence,CharSequence>>)
is undefined for the type GenericData
2) And also observed there is some deprecated code.
@Deprecated public
java.util.Map<java.lang.CharSequence,java.lang.CharSequence> VisitCommon;
I used eclipse plugin as mentioned below.
http://avro.apache.org/docs/1.7.6/mr.html
I tried with different versions of avro-maven-plugin, with 1.7.5, 1.7.6 and
with jdk1.7.0_45 version.
I am unable to resolve it.
Error message is as below:
[ERROR] symbol: method
deepCopy(org.apache.avro.Schema,java.util.Map<java.lang.CharSequence,java.lang.CharSequence>)
[ERROR] location: class org.apache.avro.generic.GenericData
Thanks & Regards,
B Anil Kumar.

Thanks Taton & Doug.
Just now, It got resolved. When I remove pig dependency from my pom, it's
stopped giving below exception.
Error: The method deepCopy(Schema, List<Map<CharSequence,CharSequence>>) is
undefined for the type GenericData
Thanks & Regards,
B Anil Kumar.

The problem with deepCopy may be a mismatch between the version of
Avro you're using at compile time and the version you're using at
runtime. When exactly are you getting this error?

Hi,
I do not know about 1), but 2) is currently expected : record fields are
public by default but tagged as deprecated - you can solve this by
explicitly asking for private fields in the Maven plugin configuration:
<plugin>
<groupId>org.apache.avro</groupId>
<artifactId>avro-maven-plugin</artifactId>
<configuration>
<fieldVisibility>private</fieldVisibility>
</configuration>
</plugin>
