java - ignite filesystem : cluster group is empty -

i'm new apache ignite , i'm trying use filesystem feature.

when using xml config file works fine, when turning conf java obtain error :

 exception in thread "main" class org.apache.ignite.igfs.igfsexception: failed execute operation because there no igfs metadata nodes.     @ org.apache.ignite.internal.processors.igfs.igfsmetamanager.runclienttask(igfsmetamanager.java:254)     @ org.apache.ignite.internal.processors.igfs.igfsimpl.mkdirs(igfsimpl.java:757)     @ org.apache.ignite.internal.processors.igfs.igfsimpl.mkdirs(igfsimpl.java:749)     @ com.test.ignitecacheclass.main(ignitecacheclass.java:171) caused by: class org.apache.ignite.cluster.clustergroupemptyexception: cluster group empty.     @ org.apache.ignite.internal.util.igniteutils$5.apply(igniteutils.java:765)     @ org.apache.ignite.internal.util.igniteutils$5.apply(igniteutils.java:763)     @ org.apache.ignite.internal.util.igniteutils.convertexception(igniteutils.java:903)     @ org.apache.ignite.internal.ignitecomputeimpl.call(ignitecomputeimpl.java:355)     @ org.apache.ignite.internal.processors.igfs.igfsmetamanager.runclienttask(igfsmetamanager.java:251)     ... 3 more caused by: class org.apache.ignite.internal.cluster.clustergroupemptycheckedexception: cluster group empty.     @ org.apache.ignite.internal.util.igniteutils.emptytopologyexception(igniteutils.java:4621)     @ org.apache.ignite.internal.processors.closure.gridclosureprocessor.callasync(gridclosureprocessor.java:584)     @ org.apache.ignite.internal.processors.closure.gridclosureprocessor.callasync(gridclosureprocessor.java:428)     @ org.apache.ignite.internal.ignitecomputeimpl.call(ignitecomputeimpl.java:352)     ... 4 more 

i've found solution while writing, have question. not working because launched client mode (obviously...). xml, without client mode explicitly set, create ignite server node.

so, decided become client of server node don't want set parameters again. isn't there way connect providing meta , data cache name filesystem name example? find dirty if store (and if works...) conf binary objects ?

i'll glad if advice me on topic :)

best regards

good evening , thank quick reply.

as said, found mistake in configuration (i think). put same boh configurations if needed. starting node client seems ran server first.

do know why need provide again config when connecting client? there way don't put entire conf when connecting client?

xml config
