Kuku1 commented on CASSANDRA-12012:
-----------------------------------
I got it running by removing the {code}Config.setClientMode(true);{code} call.
The DatabaseDescriptor checks whether isClientMode() was set to true and will
then construct a new Config instance with the standard constructor.
{code:title=org.apache.cassandra.config.DatabaseDescriptor.java|borderStyle=solid}
static
{
// In client mode, we use a default configuration. Note that the fields
of this class will be
// left unconfigured however (the partitioner or localDC will be null
for instance) so this
// should be used with care.
try
{
if (Config.isClientMode())
{
conf = new Config();
}
else
{
applyConfig(loadConfig());
}
}
catch (Exception e)
{
throw new ExceptionInInitializerError(e);
}
}
{code}
However, the field max_mutation_size_in_kb is not with a default value.
{code:title=org.apache.cassandra.config.Config.java|borderStyle=solid}
public Integer max_mutation_size_in_kb;
{code}
Besides removing the Config.setClientMode(true) I have to launch my jar with
{code}-Dcassandra.storagedir{code} and {code}-Dc
assandra.triggers_dir{code} parameters.
Thanks for your help!
