Hello Aparajita, After a quick glance on your configs and logs, I haven't found any problem with your zookeeper configs. I am not sure if you know this page, using these steps worked for me to setup a kerberized zookeeper: https://github.com/ekoontz/zookeeper/wiki I guess you are also familiar with our wiki: https://cwiki.apache.org/confluence/display/ZOOKEEPER/Client-Server+mutual+authentication
Based on your logs the problem is here: 2020-06-10 17:09:27,007 - WARN [NIOServerCxn.Factory: > 0.0.0.0/0.0.0.0:2181:ZooKeeperServer@969] - Client failed to SASL > authenticate: javax.security.sasl.SaslException: GSS initiate failed > [Caused by GSSException: Failure unspecified at GSS-API level (Mechanism > level: Invalid argument (400) - Cannot find key of appropriate type to > decrypt AP REP - AES256 CTS mode with HMAC SHA1-96)] > This is a kerberos / jaas related issue, I don't think it is zookeeper related. a few thing you might wish to check: - make sure you have "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" installed (I think you need them for AES256?) and your java security configs are OK - run "klist -e -k /etc/krb5.keytab" to see if what encryptions you have in the keytabs - check if you have full export support in JCE by "java KeyLengthDetector" - Maybe you can try with different encryption types in kerberos configs / during keytab generation. - trying to use a different java version (latest JDK patches have some known kerberos backward-incompatibilities) Unfortunately I am not a kerberos expert, so I don't know much about these issues, I just used google to find some hints :) Maybe someone else in the community with deeper kerberos knowledge can help you more.
