Much appreciated. </p> <p>I have one more question:<br /> How can I get the total number of records in column family/table under a given keyspace?</p> <p>I tried this in cql<br /> SELECT count(*) FROM abc_dimension;</p> <p>but the value is not correct.</p> <p>[Nodetool -h localhost cfstats] did not help me neither. Any better ideas?</p> <p>As a feature request, could you include this feature in the data modelling section of the Opscenter?</p> <p>Thanks again,<br /> Nish </p> http://www.datastax.com/support-forums/topic/keyspace-deletion-error-under-data-modelling-on-opscenter#post-970 Wed, 04 Jan 2012 00:45:07 +0000 nickmbailey 970@http://www.datastax.com/support-forums/ <p>This FAQ entry on the cassandra wiki explains what causes schema disagreements and how to resolve them:</p> <p><a href="http://wiki.apache.org/cassandra/FAQ#schema_disagreement" rel="nofollow">http://wiki.apache.org/cassandra/FAQ#schema_disagreement</a> </p> http://www.datastax.com/support-forums/topic/keyspace-deletion-error-under-data-modelling-on-opscenter#post-968 Tue, 03 Jan 2012 23:27:45 +0000 Anonymous 968@http://www.datastax.com/support-forums/ <p>Hi Experts,</p> <p>I am facing a pop up error while trying to delete a keyspace in cassandra which says:<br /> Error while deleting keyspace: SchemaDisagreementException()</p> <p>Tried to delete through cql which says:</p> <p>Attempt #1: Schema versions disagree, (try again later).<br /> Attempt #2: Schema versions disagree, (try again later).<br /> Attempt #3: Schema versions disagree, (try again later).<br /> Attempt #4: Schema versions disagree, (try again later).</p> <p>schema is simple.
