Bill de hOra updated CASSANDRA-358:
-----------------------------------

    Attachment: 358-1.patch

This thing really didn't want to be called twice in a running jvm. 

Changed to add 3 states

 * called and no LocationInfo CF - create it (as per current code)
 * called and LocationInfo CF found but no - bump generation it (as per current 
code)
 * called and LocationInfo CF found but we know it was just created - return 
the available LocationInfo CF  data as is

The NPE happens I think because the query filter doesn't include the token in 
its columns (generation included and found but not token). Even then you still 
need to know whether it's a restart or a new create so the first minted token 
is stashed in a static, which is how know it's just been created in this jvm 
runtime.

> While this is not the expected use case of it, SystemTable.initMetadata 
> throws an NPE when called twice in the same process.  The error points to 
> tokenColumn being null even through cf is not at line 111.
