A company named Fabrikam, Inc. has a web app. Millions of users visit the app daily.
Fabrikam performs a daily analysis of the previous day’s logs by scheduling the following Hive query.
CREATE EXTERNAL TABLE IF NOT EXISTS UserActivity (…) Partitioned BY (LogDate string) Location MSCK
REPAIR TABLE UserActivity;
Select … From UserActivity where LogDate = “{date}”;

that day.
