   This is my cluster configuration

   Whenever I insert to or list a column family I'm able to see the following error in my system.log

   ERROR [pool-2-thread-15] 2011-09-30 19:19:35,675 Cassandra.java (line 3210) Internal error processing get_range_slices

   Expecting your help. This is the second post regarding the same

   Fixed it.

   The problem is, the replication_factor by default is considered to be 3 in NetworkTopologyStrategy.
   Updated it to 1.
   But now no insertions are getting succeeded

   CounterColumnFamily

   [default@StatsKeySpace] create column family Impressions with comparator=UTF8Type and default_validation_class=CounterColumnType and key_validation_class=UTF8Type;
   175d69d0-eb6f-11e0-0000-93bbb4d362fc
   Waiting for schema agreement...
   ... schemas agree across the cluster
   [default@StatsKeySpace] incr Impressions['Test']['impressions'] by 10;
   null
   [default@StatsKeySpace] incr Impressions['Test']['impressions'] by 1;
   null

   Standard Column Family

   [default@StatsKeySpace] set TestColumnFamily['tamil']['name']=tamil;
   null

   No error in the system log even

   This is the error from my client on debug mode

   [default@StatsKeySpace] incr Impressions['tamil']['count'] by 1;
   null

   Expecting a positive reply
