Subject [jira] [Commented] (ZOOKEEPER-2843) auth_to_local should support reading rules from a file
Date Thu, 31 Jan 2019 05:43:00 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-2843?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16756891#comment-16756891
] 

Mohammad Arshad commented on ZOOKEEPER-2843:
--------------------------------------------

security.auth_to_local can also be configured without having new line character in the Rules
like security.auth_to_local=RULE:[1:$1]RULE:[2:$1]DEFAULT. In this case above discussed problems
would not occur. So the changes proposed in this JIRA are not required. We can close this
jira.

> The current handling of {{zookeeper.security.auth_to_local}} in {{KerberosName.java}}
only supports rules given directly as property value.
> These rules must therefore be given on the command line and:
> * must be escaped properly to avoid shell expansion
> * are visible in the {{ps}} output
> It would be much better to put these rules in a file and pass the file path as the property
value. We would then use something like {{-Dzookeeper.security.auth_to_local=file:/etc/zookeeper/rules}}.
> Note that using the {{file:}} prefix allows keeping backward compatibility.
