That is from Hive. http://www.reedbushey.com/99Programming%20Hive.pdf
> The database directory is created under a top-level directory specified
by the property hive.metastore.warehouse.dir, which we discussed in âLocal
Mode Configurationâ on page 24 and âDistributed and Pseudodistributed Mode
Configura- tionâ on page 26. Assuming you are using the default value for
this property, /user/hive/ warehouse, when the financials database is created,
Hive will create the directory /user/ hive/warehouse/financials.db. Note the
.db extension.
