@Geoffrey Shelton Okot Thanks for the reply, I've done the same configuration again, still I'm getting the same error. I've enabled debug logs and I found out below error:- >>>Pre-Authentication Data: PA-DATA type = 136 >>>Pre-Authentication Data: PA-DATA type = 19 PA-ETYPE-INFO2 etype = 18, salt = MSTORM.COMhbasehbase1-devup.mstorm.com, s2kparams = null PA-ETYPE-INFO2 etype = 23, salt = MSTORM.COMhbasehbase1-devup.mstorm.com, s2kparams = null PA-ETYPE-INFO2 etype = 16, salt = MSTORM.COMhbasehbase1-devup.mstorm.com, s2kparams = null >>>Pre-Authentication Data: PA-DATA type = 2 PA-ENC-TIMESTAMP >>>Pre-Authentication Data: PA-DATA type = 133 >>> KdcAccessibility: remove ambari-devup.mstorm.com >>> KDCRep: init() encoding tag is 126 req type is 11 >>>KRBError: cTime is Sat Aug 28 17:12:22 UTC 2032 1977325942000 sTime is Wed Mar 07 10:15:19 UTC 2018 1520417719000 suSec is 507841 error code is 25 error Message is Additional pre-authentication required cname is hbase/hbase1-devup.mstorm.com@MSTORM.COM sname is krbtgt/MSTORM.COM@MSTORM.COM eData provided. msgType is 30 >>>Pre-Authentication Data: PA-DATA type = 136 >>>Pre-Authentication Data: PA-DATA type = 19 PA-ETYPE-INFO2 etype = 18, salt = MSTORM.COMhbasehbase1-devup.mstorm.com, s2kparams = null PA-ETYPE-INFO2 etype = 23, salt = MSTORM.COMhbasehbase1-devup.mstorm.com, s2kparams = null PA-ETYPE-INFO2 etype = 16, salt = MSTORM.COMhbasehbase1-devup.mstorm.com, s2kparams = null >>>Pre-Authentication Data: PA-DATA type = 2 PA-ENC-TIMESTAMP >>>Pre-Authentication Data: PA-DATA type = 133 KRBError received: NEEDED_PREAUTH KrbAsReqBuilder: PREAUTH FAILED/REQ, re-send AS-REQ Followed by above error, I'm using sample test example to check whether table present or not in HBase.

Thank you in advance.
