Hi @zero , Did you try out commenting the renew_lifetime parameter in /etc/krb5.conf. I think I too had the same issue and this resolved my error. Mine was a CDP 7.1.4 cluster, but have faced similar issues in HDP also. https://community.cloudera.com/t5/Support-Questions/HDF-Zookeeper-server-not-starting-after-MIT-Kerberos-is/m-p/291367 Thanks, Vivek
