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 ...

Dear All, I have ran into a very troublesome issue which is creating headache for the last 1 week. I installed and HDF Cluster(v3.4.1.1) with the services Nifi,Kafka,Metrics and Smart Sense. Everything was working perfectly until I decided to enable Kerberos(MIT) in the cluster. During the keberization, everything went fine till the last step.(Start and Test services). At that point, the Zookeeper server start got failed and thereafter no services are starting. The following is the error I got from the zookeeper logs.Any help is appreciated.   2020-03-06 18:38:51,489 - INFO [main:QuorumPeerMain@127] - Starting quorum peer 2020-03-06 18:38:51,552 - ERROR [main:QuorumPeerMain@89] - Unexpected exception, exiting abnormally java.io.IOException: Could not configure server because SASL configuration did not allow the ZooKeeper server to authenticate itself properly: javax.security.auth.login.LoginException: Message stream modified (41) at org.apache.zookeeper.server.ServerCnxnFactory.configureSaslLogin(ServerCnxnFactory.java:207) at org.apache.zookeeper.server.NIOServerCnxnFactory.configure(NIOServerCnxnFactory.java:87) at org.apache.zookeeper.server.quorum.QuorumPeerMain.runFromConfig(QuorumPeerMain.java:130) at org.apache.zookeeper.server.quorum.QuorumPeerMain.initializeAndRun(QuorumPeerMain.java:111) at org.apache.zookeeper.server.quorum.QuorumPeerMain.main(QuorumPeerMain.java:78)   Note : I tried setting the following resolutions that I found online.

@Shelton  Dear Shelton, The cluster is running fine.. /etc/hosts on the edge node does not have entries for namenodes. I will check whether the ip's are resolving.. Is it because of the connectivity issue that I am getting GSS Exception also....?? ... View more
