Subject [jira] [Updated] (AMBARI-14373) If a bunch of RMF resources is defined using list of names, list is modified in runtime
Date Mon, 14 Dec 2015 21:10:50 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-14373?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Hurley updated AMBARI-14373:
-------------------------------------
    Description: 
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}

  was:
