Hi All,
For SSO spark login exception :
SASL authentication failed:
-- caused by: javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Illegal key size)]
the following is the solution :-)
Most likely you don't have the unlimited strength file installed :
You may need to download this file and replace this in the spark jre.
Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 6
Install the file in ${java.home}/jre/lib/security/.
