------------------------------------------

             Summary: Replication Strategy creation errors are lost in try/catch
                 Key: CASSANDRA-8909
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8909
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Alan Boudreault
            Assignee: Alan Boudreault
            Priority: Trivial
             Fix For: 2.0.13
         Attachments: replication-strategy-exception-2.0.patch

I was initially executing a bad cassandra-stress command  and was getting this error:
{code}
Unable to create stress keyspace: Error constructing replication strategy class
{code}
with the following command:
{code}
cassandra-stress -o insert --replication-strategy NetworkTopologyStrategy --strategy-properties dc1:1,dc2:1 --replication-factor 1
{code}

After digging in the code, I noticed that the error displayed was not the one thrown by the replication strategy code and that the try/catch block could be improved. Basically, the Constructor.newInstance can throw an InvocationTargetException, which provide a better error report.

I think this improvement can also be done in 2.1 (not tested yet). If my attached patch is acceptable, I will test and provide the right version for 2.1 and trunk.
