@Sampath Kumar, don't think you got any error to configuring the HA in kerberized cluster. Just take care of the steps which we execute while configuring the namenode HA. Ambari will take care of your kerberos related options.

Note: First made your topology file. Please find an attached example. knox-topology-file.xml knox-ad-ldap-upgraded-docus.pdf Above PDF file covered all practical concepts and some theory part. Step 1:- Install Knox on edge node or any node on the cluster. Step 2:- Start Knox service from Ambari,make sure your Ambari Server is already sync with LDAP. Step3:- Search your LDAP Server via below command ldapsearch -W -H ldap://ad2012.ansari.net -D binduser@ansari.net -b "dc=ansari,dc=net" ldapsearch -W -H ldaps://ad2012.ansari.net -D binduser@ansari.net -b "dc=ansari,dc=net" Step 4:- Create a master password for Knox: /usr/hdp/current/knox-server/data/security/keystores/gateway.jks /usr/hdp/2.6.4.0-91/knox/bin/knoxcli.sh create-master --force enter password then verify it Note:- (2.6.4.0-91 is my HDP versions select your hdp version /usr/hdp/XXXXXXX/) Step 5: Validate your topology file (your cluster name and toplogy file name should be same):- /usr/hdp/2.6.0.3-8/knox/bin/knoxcli.sh validate-topology --cluster walhdp Stpe 6: Validate your auth users:- sudo /usr/hdp/2.6.4.0-91/knox/bin/knoxcli.sh --d system-user-auth-test --cluster walhdp Step 7:- Change all below property and restart required services:- HDFS:- Core-site.xml: hadoop.proxyuser.knox.groups=* hadoop.proxyuser.knox.hosts=* HIVE:- webhcat.proxyuser.knox.groups=* webhcat.proxyuser.knox.hosts=* hive.server2.allow.user.substitution=true hive.server2.transport.mode=http hive.server2.thrift.http.port=10001 hive.server2.thrift.http.path=cliservice Oozie oozie.service.ProxyUserService.proxyuser.knox.groups=* oozie.service.ProxyUserService.proxyuser.knox.hosts=* Step 7 :- Try to access HDFS list status:- curl -vvv -i -k -u binduser -X GET https://hdp-node1.ansari.net:8443/gateway/walhdp/webhdfs/v1?op=LISTSTATUS curl -vvv -i -k -u binduser -X GET https://namenodehost:8443/gateway/walhdp(clustername)/webhdfs/v1?op=LISTSTATUS Step 8:- Try to access hive beeline !connect jdbc:hive2://hdp node1.ansari.net:8443/;ssl=true;sslTrustStore=/home/faheem/gateway.jks;trustStorePassword=bigdata;transportMode=http;httpPath=gateway/walhdp/hive entery username: binduser password for binduser: XXXXXXXXXX Step 9: To access Web UI’s via knox using below lines:- Ambari Ui access https://ambari-server-fqdn-or ambari-server-ip:8443/gateway/walhdp/ambari/ HDFS UI's access https://namenode-fqdn:8443/gateway/walhdp/hdfs/ HBase access https://hbase-master-fqdn:8443/gateway/walhdp/hbase/webui/ YARN UI's https://yarn-master-fqdn:8443/gateway/walhdp/yarn/cluster/apps/RUNNING Resource Manager:- https://resource-manager-fqdn:8443/gateway/walhdp/resourcemanager/v1/cluster curl -ivk -u binduser:Ansari123 " https://hdp-node3.ansari.net:8443/gateway/walhdp/resourcemanager/v1/cluster" curl -ivk -u binduser:Ansari123" https://localhost:8443/gateway/walhdp/resourcemanager/v1/cluster" Ranger Web UI's https://ranger-admin-fqdn:8443/gateway/walhdp/ranger/index.html OOzie UI's https://oozie-server-fqdn:8443/gateway/walhdp/oozie/ Zeppline https://zeppline-fqdn:8443/gateway/walhdp/zeppelin/ Thanks Ansari Faheem Ahmed HDPCA Certified
