>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 2.2.0
>            Reporter: Dmitry Lysnichenko
>            Assignee: Andrew Onischuk
>             Fix For: 2.3.0

> Given code like
> {code}
> base_dirs = [params.kafka_log_dir, params.kafka_pid_dir, params.conf_dir]
> Directory(base_dirs,
> mode=0755,
> cd_access='a',
> owner=params.kafka_user,
> group=params.user_group,
> recursive=True
> )
> set_dir_ownership(base_dirs)
> {code}
> base_dirs becomes empty after using it in Directory definition (there is a side effect
here)
> A requirement for this Jira is to remove the shallow copy slice in {{kafka.py}}:
> {code}
>  Directory(kafka_data_dirs[:],  # Todo: remove list copy when AMBARI-14373 is fixed
> {code}
