@xpelive Just want to make sure a couple configurations. 1. The port you are using in the URL (8180) is the "nifi.web.http.port=" and not the "nifi.remote.input.socket.port=" port configured in your nifi.properties file. 2. When you start your NiFi instance, you will see a line output in the nifi-app.log when startup is complete that says the NiFi Ui is available at the following URLs: Is "localhost:8180" listed in one of those URLs? If not, you need to use one of the URLs listed in your Remote Process Group. It might be that localhost is bound to a different NIC on your server than what NiFi is listening on. 3. If you have or will ever have more than 1 NiFi node in a NiFi cluster, using "localhost" is not going to work. Your NiFi nodes should be configured to use the actual hostnames fo the server on which the service is running. That hostname should be configured in both these properties: --- nifi.remote.input.host= --- nifi.web.http.host= 4. Since your NiFi is not secured, make sure that your nifi.properties file is not configured to be secure: nifi.remote.input.secure=false. Null exceptions are particularly difficult to diagnose because a null basically means there was no error handling coded to handle to particular exception. Thus we need o look at all angles of the configuration to see where the issue may reside.

Hi @forest lin , Can you please pause the upgrade, Make the configuration change and Try to resume the upgrade? As per current ambari design once upgrade is going on all configuration changes will be at paused stage. Thanks, Akhil

It's caused by missing file in folder dists in HDP-UTILS-1.1.0.22-ubuntu16.tar.gz and fixed as following after getting the advice from a HDP consultant 1. extract HDP-UTILS-1.1.0.22-ubuntu16.tar.gz 2. mkdir HDP-UTILS under folder dists 3. copy all files from HDP repot /hdp/HDP/ubuntu16/2.6.5.0-292/dists/HDP/ to above HDP-UTILS folder 4 update the HDP-UTILS repo base url according to https://docs.hortonworks.com/HDPDocuments/Ambari-2.7.0.0/bk_ambari-installation/content/setting_up_a_local_repository_with_no_internet_access.html

@forest lin then that is possibly a different issue. Initially you were getting java.lang.NoSuchMethodError: org.apache.phoenix.spark.DataFrameFunctions.saveToPhoenix$default$4()Lscala/Option; and only for spark 2 you are now getting Userclass threw exception: java.lang.NoClassDefFoundError: org/apache/spark/sql/DataFrame Please review the following link https://community.hortonworks.com/content/supportkb/150292/errorexception-in-thread-main-javalangnoclassdeffo.html Also I think is best to take this error in separate thread as is not same as the initial problem which got solved by adding the configuration I mentioned before.

@forest lin The kdc.conf looks fine, but your initial and final krb5.conf don't look correct you forgot to add the entry in lowercase see below !. Please backup of your current krb5.conf on all the hosts and replace them with the below exactly as it is. [libdefaults]
renew_lifetime = 7d
forwardable = true
default_realm = ABC.COM
ticket_lifetime = 24h
dns_lookup_realm = false
dns_lookup_kdc = false
default_ccache_name = /tmp/krb5cc_%{uid}
#default_tgs_enctypes = aes des3-cbc-sha1 rc4 des-cbc-md5
#default_tkt_enctypes = aes des3-cbc-sha1 rc4 des-cbc-md5
[domain_realm]
abc.com = ABC.COM
.abc.com = ABC.COM
[logging]
default = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log
kdc = FILE:/var/log/krb5kdc.log
[realms]
ABC.COM = {
admin_server = nn1-dev1-tbdp
kdc = nn1-dev1-tbdp
} Did you re-run the below to correctly setup the KDC and KDC Admin hostnames dpkg-reconfigure krb5-kdc Can you also validate that the host entries on all the hosts are the same and include the KDC server host entry? What the content of your kadm5.acl file? On the KDC server can you paste the output of the below command. Please obscure the domain name # kdestroy
# kadmin.local
Authenticating as principal root/admin@ABC.COM with password.
kadmin.local: listprincs After validating and changing the above restart the services service krb5-kdc restart
service krb5-admin-server restart Don't forget to enable auto-restart of kdc and kadmin use appropriate ubuntu command chkconfig krb5kdc on
chkconfig kadmin on Now try the Ambari--> Kerberos wizard again it should succeed The logs are in these directories on the KDC and Clients default = /var/log/krb5kdc.log
admin_server = /var/log/kadmind.log
kdc = /var/log/krb5kdc.log Please revert
