Hi,

I'm back looking at the Cassandra tests again and I've nearly cracked them.

What I don't understand is how to obtain the mapping's from
conf/gora-cassandra-mapping.xml?

What I have so far is

lewis@lewis-01:~/ASF/gora/gora-cassandra/src/test$ tree
.
=E2=94=9C=E2=94=80=E2=94=80 conf
=E2=94=82   =E2=94=9C=E2=94=80=E2=94=80 cassandra.yaml
=E2=94=82   =E2=94=9C=E2=94=80=E2=94=80 gora-cassandra-mapping.xml

                =E2=94=94=E2=94=80=E2=94=80 cassandra
                    =E2=94=9C=E2=94=80=E2=94=80 GoraCassandraTestDriver.jav=
a
                    =E2=94=94=E2=94=80=E2=94=80 store
                        =E2=94=94=E2=94=80=E2=94=80 TestCassandraStore.java


Looking at the TestHbaseStore I see that we call

  @Override
  public void setUp() throws Exception {
    super.setUp();
    conf =3D getTestDriver().getHbaseUtil().getConfiguration();
  }

Is this what is required to obtain the mapping configuration? This is easy
using HBaseTestingUtility as it's a method in the class, unfortunately
neither CassandraDaemon (Cassandra API) nor EmbeddedServerHelper (Hector
API) have this method to simply call on...

When I try to run my tests my Cassandra configuration is fine, but no
mapping seems to be retrieved and most of the test log output complains

  testTruncateSchema(org.apache.gora.cassandra.store.TestCassandraStore):
org.apache.avro.generic.GenericArray.add(Ljava/lang/Object;)V
  testTruncateSchema(org.apache.gora.cassandra.store.TestCassandraStore):
InvalidRequestException(why:Keyspace does not exist.)

This is because I'm not picking up the mappings from conf. I've uploaded my
latest patch to Jira @ GORA-53-v8.patch ha ha ha!!! I would seriously
appreciate if someone could shine some light on it for me/put me out my
misery/stop me from going insane in the membrane... etc.

This is driving me mad.

Thanks

Lewis
