> 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).
