    Description

      I get multiple NullPointerException when trying to trace INSERT statements.

      To reproduce:

      $ ccm create -v git:trunk
      $ ccm populate -n 3
      $ ccm start
      $ ccm node1 cqlsh < 5668_npe_ddl.cql
      $ ccm node1 cqlsh < 5668_npe_insert.cql
      

      And see many exceptions like this in the logs of node1:

      ERROR [WRITE-/127.0.0.3] 2013-06-19 14:54:35,885 OutboundTcpConnection.java (line 197) error writing to /127.0.0.3
      java.lang.NullPointerException
              at org.apache.cassandra.net.OutboundTcpConnection.writeConnected(OutboundTcpConnection.java:182)
              at org.apache.cassandra.net.OutboundTcpConnection.run(OutboundTcpConnection.java:144)
      

      This is similar to CASSANDRA-5658 and is the reason that npe_ddl and npe_insert are separate files.
