Description

Given code like

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)

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:

 Directory(kafka_data_dirs[:],  # Todo: remove list copy when AMBARI-14373 is fixed
