Hi @araujo    What are the symptoms of the ticket renewal failure? Are there any error messages anywhere? > We see GSSException on Application logs   How did you conclude it's a ticket renewal problem? > We haven’t concluded its a renewal problem however to rule out kerberose issue, we need logs which at the present is not getting written in the location specified in krb5.conf file.   Thanks  Wert ...

Hi @araujo, Yes we are using MIT Kerberose, below is the configs of /var/kerberos/krb5kdc/kdc.conf   [kdcdefaults] kdc_ports = 88 kdc_tcp_ports = 88 [realms] MY_COMPANY.COM = { #master_key_type = aes256-cts acl_file = /var/kerberos/krb5kdc/kadm5.acl dict_file = /usr/share/dict/words max_renewable_life = 7d 0h 0m 0s forwardable = true udp_preference_limit = 1 admin_keytab = /var/kerberos/krb5kdc/kadm5.keytab supported_enctypes = aes256-cts:normal aes128-cts:normal des3-hmac-sha1:normal arcfour-hmac:normal camellia256-cts:normal camellia128-cts:normal des-hmac-sha1:normal des-cbc-md5:normal des-cbc-crc:normal  default_principal_flags = +renewable, +forwardable database_name = /opt/localkrb5/krb5kdc/principal } I do not see any infomation about logging in this.     Regarding the second issue I have found a solution - https://my.cloudera.com/knowledge/Logs-are-not-updating-in-varloghue-after-upgrading-to-CDH-6?id=87842    Thanks  Wert ...

Hi @araujo  Appericate your reply, regarding the first part of the question, I am trying to check the KDC server logs to troubleshoot an issue wherein an application is unable to renew its ticket, hence wanted to check the logs. Now for the second issue, the logs are not getting written in /var/log/hue/ (on the host where the roles are configured) for kt_renewer.log & runcpserver.log as the timestamp on both on them show Nov 24. There is ample Disk Space available.   Thanks  Wert ... View more
