Great article! I faced the following error while trying adding data to ldap (Step 13.)   # ldapadd -x -W -D "cn=Manager,dc=example,dc=com" -f /root/ldap/base.ldif Enter LDAP Password: adding new entry "dc=example,dc=com" ldap_add: Invalid syntax (21) additional info: objectClass: value #1 invalid per syntax   After some research, found that we need to add the cosine and nis LDAP schemas before running the preceding command.    # ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/cosine.ldif # ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/nis.ldif # ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/inetorgperson.ldif ...

SYMPTOM: While performing HDP upgrade [HDP-2.3.0 upgrade to HDP-2.5.3] there was error for which we had to start ambari server.

Check for latest version and repo_version_id from above command and modified respective repo_version_id in "host_version" table pointing the status to CURRENT and made rest of the entries to INSTALLED. So the output should look like below - ambari=> select * from host_version; id | repo_version_id | host_id | state ----+-----------------+---------+--------- 1 | 1 | 1 | INSTALLED 2 | 1 | 3 | INSTALLED 3 | 2 | 2 | CURRENT 4.
