Hi all, In Ignite 1.3.0-incubating I was able to populate a cache on my grid with data via a DataStreamer running in Daemon-mode. From Ignite 1.4 I get a "Cache doesn't exist".
I'm not sure if this is a issue with my approach to data-loading and is therefore a deliberate feature change? My approach so far has been to start-up a number of "data-nodes", then run the data-load via a separate Java process. I'm happy to take pointers on a better way. I've reproduced the issue in fairly cutdown example code and you can see it at https://github.com/waters-colin/ignite-dataloading You can observe the different behaviour by changing the $IGNITE_HOME as well as the ignite dependency version in the pom. The Stack I get on error is: Exception in thread "main" java.lang.IllegalStateException: Cache doesn't exist: city-cache at org.apache.ignite.internal.processors.cache.GridCacheProcessor.cacheConfiguration(GridCacheProcessor.java:3051) at org.apache.ignite.internal.processors.datastreamer.DataStreamerImpl.<init>(DataStreamerImpl.java:240) at org.apache.ignite.internal.processors.datastreamer.DataStreamProcessor.dataStreamer(DataStreamProcessor.java:171) at org.apache.ignite.internal.IgniteKernal.dataStreamer(IgniteKernal.java:2756) at ignite.example.CityBulkLoader.loadAll(CityBulkLoader.java:28) at ignite.example.DataLoadingApp.loadData(DataLoadingApp.java:45) at ignite.example.DataLoadingApp.main(DataLoadingApp.java:64) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:144) I can see that there was a check for isDaemon() added to GridCacheProcessor.start() CacheConfiguration loop ~ line 601 and that when this check is commented that I again can use the DataStreamer ok. Is it expected to be able to use an IgniteDataStreamer from code running with Ignition.setDaemon(true)? All the best, Colin.
