@Raju It looks like you might not have setup the FQDN properly for all your hosts. (Or the hostname might have changed) Ambari associates the FQDN (hostname) in the principal name So ig you are not setting up your host FQDN properly then the keytabs might be generated with incorrect principals. Please check if your Hosts have recently changed their hostname? Vefify the output of the following command in different hosts of your cluster including the problematic host. # hostname -f # /cat /etc/hosts . Once you fix the hostname, Please try to regenerate the Keytabs from Ambari UI --> Kerberos --> Regenerate Keytabs NOTE: Regenerating Keytabs will require whole cluster restart, hence please find a maintenance window to do that. https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.2/bk_ambari-operations/content/how_to_regenerate_keytabs.html . Hadoop relies heavily on DNS, and as such performs many DNS lookups during normal operation. All hosts in your system must be configured for both forward and and reverse DNS. If you are unable to configure DNS in this way, you should edit the /etc/hosts file on every host in your cluster to contain the IP address and Fully Qualified Domain Name of each of your hosts. https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.2/bk_ambari-installation-ppc/content/check_dns.html ...

@Junfeng Chen Error indicates that the "libcurl" version which you are uisng in your Anaconda is too old and does not support "--negotiate" flag with curl command. So can you please let us know how you checked the "libcurl" and Curl version on your hosts? What version of "libcurl" do you see when you run the following command. By any chance do you have multiple Curl versions installed on the host? Example: # curl -V curl 7.29.0 (x86_64-redhat-linux-gnu) libcurl/7.29.0 NSS/3.34 zlib/1.2.7 libidn/1.28 libssh2/1.4.3 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp scp sftp smtp smtps telnet tftp Features: AsynchDNS GSS-Negotiate IDN IPv6 Largefile NTLM NTLM_WB SSL libz unix-sockets . Can you try upgrading Curl / libcurl on your host? Similar thread: https://community.hortonworks.com/questions/70994/hiveserver2-failing-with-tmptmp23xnha-2tmptmpyf2fo.html ... View more

@Anurag Mishra Do you have a valid kerberos ticket? Please check the output of the following command: # klist . If you do not have a valid kerberos ticket then please check if you have a correct keytab? If yes then please try to do a kinit something like this: First check the Principal from the keytab # klist -kte /etc/security/keytabs/hive.service.keytab Then do the kinit using that principal & keytab Following is just an example, you might have your own Keytab with your own custom principal name so you will need to do the kinit accordingly. Example: # kinit -kt /etc/security/keytabs/hive.service.keytab hive/kamb25101.example.com@EXAMPLE.COM # klist . ... View more
