> {noformat}
> *Cause*
> This is caused by one or more records with a {{NULL}} value in the {{create_time}} field.
> For example:
> ||user_id||user_name||user_type||create_time||
> |1|admin|LOCAL|NULL|
> *Workaround*
> Update the relevant records to not have a {{NULL}} in the {{create_time}} column.
> For example:
> {noformat}
> UPDATE users SET create_time=systimestamp WHERE create_time IS NULL;
> {noformat}
> *Solution*
> During upgrade, protect against a {{null}} value for {{currentUserCreateTime.getValue()}} at:
> {code:java|title=org/apache/ambari/server/upgrade/UpgradeCatalog270.java:595}
> dbAccessor.updateTable(USERS_TABLE, temporaryColumnName, currentUserCreateTime.getValue().getTime(),
> "WHERE " + USERS_USER_ID_COLUMN + "=" + currentUserCreateTime.getKey());
> {code}
> If {{currentUserCreateTime.getValue()}} is null, the current timestamp should be used.
> *Note:* This may be a reoccurring issue since there is no provision to ensure that {{create_time}} is not {{NULL}} when initializing the Ambari database:
> {code:java}
> insert into users(user_id, principal_id, user_name, user_password)
> select 1,1,'admin','538916f8943ec225d97a9a86a2c6ec0818c1cd400e09e03b660fdaaec4af29ddbb6f2b1033b81b00' from dual;{code}
