问题
The error is purely the title. Any call I do to containsKey in a map retrieved from Hazelcast I get this specific error. Example below:
val structuresMapStore : IMap[ String, Object ] = instance.getMap( MapNames.Structures )
if ( structuresMapStore.containsKey( uuidModel ) ) {
logger.info( "\n\n Server - Dropping map: " + uuidModel + "\n\n" )
structuresMapStore.remove( uuidModel )
instance.getMap( uuidModel ).destroy()
return "SUCCESS"
}
return "FAIL"

The error occurs when I call containsKey inside if statement.
回答1:
It is not allowed to make operations from MapStore interface methods in case of write through. Because writethrough map store operations run on partition thread, and using another partition based operation(like Containskey) can cause deadlock. That is why we have a check and an exception there.
