Loading configurations from classpath in class FileModuleShardConfigProvider [1] does not work properly, because it tries to read from file name instead of file path.

This is code that read configs:

Config moduleShardsConfig = null;
if (moduleShardsFile.exists())

{ LOG.info("module shards config file exists - reading config from it"); moduleShardsConfig = ConfigFactory.parseFile(moduleShardsFile); } else { LOG.warn("module shards configuration read from resource"); moduleShardsConfig = ConfigFactory.load(moduleShardsFile.getName()); // <------------------- }

Config modulesConfig = null;
if (modulesFile.exists()) { LOG.info("modules config file exists - reading config from it"); modulesConfig = ConfigFactory.parseFile(modulesFile); } else { LOG.warn("modules configuration read from resource"); modulesConfig = ConfigFactory.load(modulesFile.getName()); // <------------------- }

And it should look something like this:

Config moduleShardsConfig = null;
if (moduleShardsFile.exists()) { LOG.info("module shards config file exists - reading config from it"); moduleShardsConfig = ConfigFactory.parseFile(moduleShardsFile); }

else

{ LOG.warn("module shards configuration read from resource"); final String path = moduleShardsFile.getPath().replace("\\", "/"); // in case of windows OS moduleShardsConfig = ConfigFactory.load(path); }

Config modulesConfig = null;
if (modulesFile.exists())

{ LOG.info("modules config file exists - reading config from it"); modulesConfig = ConfigFactory.parseFile(modulesFile); }

else

{ LOG.warn("modules configuration read from resource"); final String path = modulesFile.getPath().replace("\\", "/"); // in case of windows OS modulesConfig = ConfigFactory.load(path); }
