Multi-User Group Sharing
| Info | ||
|---|---|---|
| ||
By default, when secure impersonation is enabled, you could share an artifact with a single user group only. This results out of the limitation of a standard POSIX file permission level 'user:group:others'. With the plugin 'Multiple Group Sharing by ACLs', Datameer creates a HDFS ACL for a certain file/ folder in the HDFS to reflect additional group permissions. Note that it is not supported to migrate from the ACL mode to the POSIX mode (see https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HdfsPermissionsGuide.html). The default sharing mode can be overwritten with the REST call. When the secure mode 'Native Multi User' (NMU) is enabled and the plugin 'Multiple Group Sharing by ACLs' is installed, then the multi group sharing is the default mechanism. |
Enabling Multi-User Group Sharing
To enable this functionality:
- Ensure that the HDFS ALC functionality is enabled at the Hadoop cluster.
INFO: See Enabling ACLs. - /wiki/spaces/DASSB100/pages/32569526778 the 'Multiple Group Sharing by ACLs' plug-in in Datameer's 'Admin' section.
Activate the plug-in via REST API.
INFO: This step is not required when NMU mode is activated.Request Method PUT URI Syntax Code Block curl -v -u '<user>:<password>' -X PUT 'http://host:port/api/groupPermissionMode?mode=MULTIPLE_USERS_GROUPS'Response The call should return '204 No Content' HTTP code.
