Classes in org.apache.cassandra.deps:avro:1.4.0-cassandra-1 clash with core
Avro classes
----------------------------------------------------------------------------------------
Key: CASSANDRA-4097
URL: https://issues.apache.org/jira/browse/CASSANDRA-4097
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 1.0.8
Reporter: Andrew Swan
Cassandra has this dependency:
{code:title=build.xml}...
<dependency groupId="org.apache.cassandra.deps" artifactId="avro"
version="1.4.0-cassandra-1">
...{code}
Unfortunately this JAR file contains classes in the {{org.apache.avro}} package
that are incompatible with classes of the same fully-qualified name in the
current release of Avro. For example, the inner class
{{org.apache.avro.Schema$Parser}} found in Avro 1.6.1 is missing from the
Cassandra version of that class. This makes it impossible to have both
Cassandra and the latest Avro version on the classpath (my use case is an
application that embeds Cassandra but also uses Avro 1.6.1 for unrelated
serialization purposes). A simple and risk-free solution would be to change the
package declaration of Cassandra's Avro classes from {{org.apache.avro}} to
(say) {{org.apache.cassandra.avro}}, assuming that the above dependency is only
used by Cassandra and no other projects (which seems a reasonable assumption
given its name).
