Tycho Lamerigts commented on AVRO-1638:
---------------------------------------
Although not needed to reproduce the bug, for completeness sake I will mention
that I generated the attached avro file with ReflectDatumWriter<Foo>, where Foo
is defined as
{code}
package test;
public class Foo {
private final Bar bar;
public Foo(Bar bar) {
this.bar = bar;
}
public Bar getBar() {
return bar;
}
public static class Bar {
private final String str;
public Bar(String str) {
this.str = str;
}
public String getStr() {
return str;
}
}
}
{code}
> SpecificDatumReader cannot read inner classes

> Key: AVRO-1638
> URL: https://issues.apache.org/jira/browse/AVRO-1638
> Project: Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.7.7
> Reporter: Tycho Lamerigts
> Attachments: foo.avro
>
>
> After generating Specific classes from the attached avro file's schema, the
> file's content cannot be read by the following code.
> {code}
> DatumReader<Foo> r = new SpecificDatumReader<>(Foo.class);
> DataFileReader<Foo> fr = new DataFileReader<>(new File("foo.avro"), r);
> fr.next(); // this will throw
> {code}
> It appears to me that the logic in SpecificData#getClassName for dealing with
> names ending with '$' is incorrect, which causes avro to fall back to
> GenericDatumReader and ultimately fail.
