How can I check what the consistency level is?
We seem to be having issues with out Consistency policies. We have it
configured in Spring using the following:
<bean id="consistencyLevelPolicy" class=
"me.prettyprint.cassandra.model.ConfigurableConsistencyLevel">
<property name="defaultReadConsistencyLevel" value="LOCAL_QUORUM"/>
<property name="defaultWriteConsistencyLevel" value="LOCAL_QUORUM"/>
</bean>
<bean id="keyspaceOperator" class=
"me.prettyprint.hector.api.factory.HFactory" factory-method="createKeyspace"
>
<constructor-arg value="RegistryFoundation"/>
<constructor-arg ref="cluster"/>
<constructor-arg ref="consistencyLevelPolicy"/>
</bean>
However, in our distributed testing, bringing down a single node will cause
the 'May not be enough replicas present to handle consistency level' error
I wanted to create a test to load the Spring config (above) and find out
what the consistency level is set to but there do not appear to be any
accessor methods to discover the value. Is there a way to output the
Consistency level to make sure that what we have configured is what is
actually being used?

Well I did a local test by debugging our code and the policy is set to
LOCAL_QUORUM. Is there something else I'm missing? More info that would
help? Or should I direct this to the hector-users group?

If you turn the server logging up to DEBUG you will see what CL the client is sending.
