I am unable to start the Clickhouse-local with --config-file option , However clickhouse-server is running with same configuration xml files.

I am getting below error :

After debugging , It seems that Clickhouse-local is searching for "<users_config>" in config() and if not , setting the user_config_path to config.xml. Since config.xml doesn't have any user related storage info, throwing error.
https://github.com/ClickHouse/ClickHouse/blob/master/programs/local/LocalServer.cpp#L328

Adding <users_config> in config.xml loaded the user configuration successfully , However it fails with default database exists error. Since Clickhouse-local already creates default database as part of DatabaseMemory and try to create database again here.

PS: , In clickhouse-server, CH automatically searches for user.xml in same path as in config.xml. There is no constraint with <users_config> tag .
