Hi Folks,
Right now I'm going through gora-cassandra module [0] with a fine tooth-comb trying to improve it.
I'm injecting URLs into Cassandra and using hector 1.1-0 with 1.1.12 and seeing >1 "keyspace reseting from null to webpage" DEBUG messages from HThriftClient#getCassandra method [1] within my logs.
The thing which is puzzling me right now is why the following statement seems to be true [2]

if ( keyspaceNameArg != null && !StringUtils.equals(keyspaceName, keyspaceNameArg)) {

An example of the logging is as follows

2014-01-22 21:28:06,728 DEBUG client.HThriftClient - keyspace reseting from null to webpage

However, if I've already/previously established the keyspace as 'webpage' why is it always 'null'?

Any hints are really appreciated.
Thank you
Lewis

That message simply means that the particular Cassandra.Client had not
been used yet with an operation that required a keyspace.
