Security considerations

Kudu includes security features that allow Kudu clusters to be hardened against access from unauthorized users.

Kudu 1.3 (and higher) includes security features that allow Kudu clusters to be hardened against access from unauthorized users. Kudu uses strong authentication with Kerberos, while communication between Kudu clients and servers can now be encrypted with TLS. Kudu also allows you to use HTTPS encryption to connect to the web UI.

These security features should work seamlessly in Impala as well, as long as Impala’s user is given permission to access Kudu.
