-------------------------------------
Summary: SchemaCompatibility class could be more user-friendly
about incompatibilities
Key: AVRO-1933
URL: https://issues.apache.org/jira/browse/AVRO-1933
Project: Avro
Issue Type: Improvement
Components: java
Affects Versions: 1.8.1
Environment: Any Java env
Reporter: Anders Sundelin
Priority: Minor
Fix For: 1.9.0
Today, the class SchemaCompatibility reports incompatibilities with quite
little detail. The whole reader and the whole writer schema is listed, and no
particular detail about what was incompatible.
The attached patch fixes this, introducing a new enum
(SchemaIncompatibilityType), and more specific sub-schemas that were
incompatible.
The old, overall picture, is still there - the new compatibility state is
encapsulated in the SchemaCompatibilityDetails class.
Lots of test cases have been added, and there has been refactoring done in the
TestSchemaCompatibility and other test classes.
