Enabling LDAP Authentication for impala-shell

To connect to Impala using LDAP authentication, you specify command-line options to the impala-shell command interpreter and enter the password when prompted.

-l

Enables LDAP authentication.

-u

Sets the user. Per Active Directory, the user is the short username, not the full LDAP distinguished name. If your LDAP settings include a search base, use the --ldap_bind_pattern on the impalad daemon to translate the short user name from impala-shell automatically to the fully qualified name.

impala-shell automatically prompts for the password.
