Subject [jira] [Updated] (YARN-6447) Provide container sandbox policies for groups
Date Thu, 06 Apr 2017 14:57:41 GMT

     [ https://issues.apache.org/jira/browse/YARN-6447?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Greg Phillips updated YARN-6447:
--------------------------------
    Attachment: YARN-6447.001.patch

Small patch to allow groups to be mapped to custom Java Security Manager policy files using
the following yarn-site configuration:
yarn.nodemanager.runtime.linux.sandbox-mode.policy.group.$groupName

If a given user is a member of multiple groups with custom policy files, the user will receive
the superset of all permissions from the groups to which they belong.

> Currently the container sandbox feature ([YARN-5280|https://issues.apache.org/jira/browse/YARN-5280])
allows YARN administrators to use one Java Security Manager policy file to limit the permissions
granted to YARN containers.  It would be useful to allow for different policy files to be
used based on groups.
> For example, an administrator may want to ensure standard users who write applications
for the MapReduce or Tez frameworks are not allowed to open arbitrary network connections
within their data processing code.  Users who are designing the ETL pipelines however may
need to open sockets to extract data from external sources.  By assigning these sets of users
to different groups and setting specific policies for each group you can assert fine grained
control over the permissions granted to each Java based container across a YARN cluster.
