I am running ambari-server with root user. When I was enabling kerberos."sudo: no tty present and no askpass program specified" just occured on step 7 "Kerberize Cluster-Configure Ambari Identity". Do I have to visudo as non-root user ? I really puzzled. Please help me figure that out. This is my ambari-audit.log ...... 2018-07-20T01:15:02.488+0800, Operation(Keytab file creation), Status(Success), RequestId(281), TaskId(4736), Principal(ambari-qa@flx.com), Hostname(flx93), Keytab file(/etc/security/keytabs/smokeuser.headless.keytab) 2018-07-20T01:15:02.489+0800, Operation(Keytab file creation), Status(Success), RequestId(281), TaskId(4736), Principal(ambari-server@flx.com), Hostname(ambari_server), Keytab file(/etc/security/keytabs/ambari.server.keytab) 2018-07-20T01:15:02.490+0800, Operation(Keytab file creation), Status(Success), RequestId(281), TaskId(4736), Principal(HTTP/flx86@flx.com), Hostname(ambari_server), Keytab file(/var/lib/ambari-server/data/tmp/.ambari_1532020473683-0.d/ambari_server/8d4cb8842a900d56fe6d3030b414b50634cfdf54) 2018-07-20T01:15:02.518+0800, User(admin), Operation(EXECUTE AMBARI_SERVER_ACTION), Details(Create Keytabs), Status(COMPLETED), RequestId(281), TaskId(4736), Hostname(null) 2018-07-20T01:15:02.985+0800, User(admin), Operation(EXECUTE AMBARI_SERVER_ACTION), Details(Configure Ambari Identity), Status(QUEUED), RequestId(281), TaskId(4737), Hostname(null) 2018-07-20T01:15:02.998+0800, User(admin), Operation(EXECUTE AMBARI_SERVER_ACTION), Details(Configure Ambari Identity), Status(IN_PROGRESS), RequestId(281), TaskId(4737), Hostname(null) 2018-07-20T01:15:03.062+0800, User(admin), Operation(Preparing Operations), Status(FAILED), RequestId(281) 2018-07-20T01:15:03.062+0800, User(admin), Operation(EXECUTE AMBARI_SERVER_ACTION), Details(Configure Ambari Identity), Status(FAILED), RequestId(281), TaskId(4737), Hostname(null) 2018-07-20T01:15:04.012+0800, User(admin), Operation(CUSTOM_COMMAND KERBEROS_CLIENT), Details(SET_KEYTAB KERBEROS/KERBEROS_CLIENT), Status(ABORTED), RequestId(281), TaskId(4738), Hostname(flx86) 2018-07-20T01:15:04.012+0800, User(admin), Operation(CUSTOM_COMMAND KERBEROS_CLIENT), Details(SET_KEYTAB KERBEROS/KERBEROS_CLIENT), Status(ABORTED), RequestId(281), TaskId(4739), Hostname(flx87) 2018-07-20T01:15:04.012+0800, User(admin), Operation(CUSTOM_COMMAND KERBEROS_CLIENT), Details(SET_KEYTAB KERBEROS/KERBEROS_CLIENT), Status(ABORTED), RequestId(281), TaskId(4740), Hostname(flx89) 2018-07-20T01:15:04.012+0800, User(admin), Operation(CUSTOM_COMMAND KERBEROS_CLIENT), Details(SET_KEYTAB KERBEROS/KERBEROS_CLIENT), Status(ABORTED), RequestId(281), TaskId(4741), Hostname(flx90) 2018-07-20T01:15:04.012+0800, User(admin), Operation(CUSTOM_COMMAND KERBEROS_CLIENT), Details(SET_KEYTAB KERBEROS/KERBEROS_CLIENT), Status(ABORTED), RequestId(281), TaskId(4742), Hostname(flx91) 2018-07-20T01:15:04.012+0800, User(admin), Operation(CUSTOM_COMMAND KERBEROS_CLIENT), Details(SET_KEYTAB KERBEROS/KERBEROS_CLIENT), Status(ABORTED), RequestId(281), TaskId(4743), Hostname(flx92) 2018-07-20T01:15:04.012+0800, User(admin), Operation(CUSTOM_COMMAND KERBEROS_CLIENT), Details(SET_KEYTAB KERBEROS/KERBEROS_CLIENT), Status(ABORTED), RequestId(281), TaskId(4744), Hostname(flx93) 2018-07-20T01:15:04.012+0800, User(admin), Operation(Preparing Operations), Status(ABORTED), RequestId(281) 2018-07-20T01:15:04.012+0800, User(admin), Operation(EXECUTE AMBARI_SERVER_ACTION), Details(Update Service Configurations), Status(ABORTED), RequestId(281), TaskId(4745), Hostname(null) This is my ambari-server.log ...... 20 Jul 2018 01:15:02,432 INFO [Server Action Executor Worker 4736] CreateKeytabFilesServerAction:193 -
