Subject Re: Problems using Thrift API in C
Date Fri, 29 Jul 2011 10:26:09 GMT
We have installed Thrift from the official repository (trunk, revision 
1152120) and our code now sets keyspace successfully. Apparently, a 
related bug has been fixed in Thrift after the release of Thrift 0.6.1.

We shall share some example C code if we manage to get this working.
