while setting up kerberos on ambari 2.7.4 and HDP 3 iI got this error message
Caused by: org.apache.ambari.server.serveraction.kerberos.KerberosOperationException: Unexpected error condition executing the kadmin command. STDERR: kadmin: Matching credential not found (filename: /tmp/ambari_krb_142308985016794830cc) while initializing kadmin interface
and I’m sure the krb5.conf and kdc.conf configuration are fine.
kerberos tested on shell everything looks fine.
any suggestions? BR,
