@Anurag Mishra Are the ports listed here open in your network settings? May be you can check the ambari-server.log for any clue and do a telnet <ambari-server> 8080 from the machine you are trying to access to see if you are able to reach host and port.

@Jacqualin jasmin By Default spark will take care of renewing kerberos ticket when it is about to expire. So you need not make any changes.

@Vijay Mishra One quick thing you can do is to change the kafka root zk node (this is create a new znode and kafka will not have any reference of any old data). zookeeper.connect=zk1:2181,zk2:2181,zk3:2181/kafka or you need to enable the kerberos again and change the ACl's using below commands (Kafka will have old data) : Log-in as user "kafka" on one of Kafka nodes:
kinit -k -t /etc/security/keytabs/kafka.service.keytab kafka/_HOST
where _HOST should be replaced by the hostname of that node
Run the following command to open zookeeper shell:
/usr/hdp/current/kafka-broker/bin/zookeeper-shell.sh zkhostname:2181
setAcl /brokers world:anyone:crdwa
setAcl /config world:anyone:crdwa
setAcl /controller world:anyone:crdwa
setAcl /admin world:anyone:crdwa
Post changing the acl's disable the kerberos.

@Vijay Mishra zookeeper acl's needs to be changed before disabling the kerberos. Do you have any important data in kafka?

@Pee Tankulrat, As Rahul mentioned you need to make sure that policy is not failing back to POSIX permission. And for group policy issue, you may ask another question with more details.

@Gunnar Anderson The logs should be at /var/log/nifi/nifi-app.log in all the nifi nodes. You can also use Log Search (if it is installed in your environment) to see the pattern and play with the log using UI.

@Pee Tankulrat Yes, the policy usually denied all except when there's an access policy for it. This should be ok.
