The security settings for the various MapRMaoR ecosystem components are as follows:

Security Settings for Hadoop/Yarn

File or command: core-default.xml
Description: Authentication used for the HTTP web-consoles
Default Secure Setting: hadoop.http.authentication.type:org.apache.hadoop.security.authentication.server.MultiMechsAuthenticationHandler
Alternate Value or Change Command: simple | kerberos | #AUTHENTICATION_HANDLER_CLASSNAME#

If connecting to an LDAP server with a non-AD schema, replace the default filter with (&(objectClass=inetOrgPerson)(uid={0}). {0} is a special string used to denote where the username fits into the filter. If the LDAP server supports posixGroups, Hadoop can enable the feature by setting the value of this property to posixAccount and the value of the hadoop.security.group.mapping.ldap.search.filter.group property to posixGroup.

Alternate Value or Change Command: None
Notes: The default implementation org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback determines if the Java Native Interface (JNI) is available. If JNI is available, the implementation uses the API within Hadoop to resolve a list of groups for a user. If JNI is not available, then the shell implementation ShellBasedUnixGroupsMapping, is used.

For example, a group entry for fooGroup containing member : uid=fooUser,ou=Users,dc=domain,dc=com helps determine that fooUser belongs to LDAP group fooGroup.

See Group Membership for a detailed example. You can use this property to find the users, if a custom-configured LDAP query returns a group instead of a user (as of Hive 2.1.1). For details, see Support for Groups in Custom LDAP Query.

Description: This property indicates the prefix to use when building the bindDN for LDAP connection (when using only baseDN).
Default Secure Setting: hive.server2.authentication.ldap.guidKey:uid

  • auth – authentication only (default)
  • auth-int – authentication plus
  • integrity protection auth-conf – authentication plus integrity and confidentiality protection
Notes: Note that setting hadoop.rpc.protection to a higher level than HiveServer2 does not make sense in most situations. HiveServer2 ignores hadoop.rpc.protection in favor of hive.server2.thrift.sasl.qop. This setting is applicable only if HiveServer2 is configured to use Kerberos authentication.
