Sergio Peña commented on HIVE-10658:
------------------------------------
Doesn't ACID get the scratch directory from the Context object?
The {{SemanticAnalyzer.getMetaData()}} gets the encrypted or /tmp directory
from getStagingDirectoryPathname() and sets the value to the Context.
This might help. See the line {{Path stagingPath =
getStagingDirectoryPathname(qb);}}
> ACID operation expose encrypted data

> Insert/Update/Delete operations all use temporary tables.
> the data in temp tables is stored under the hive.exec.scratchdir which is not
> usually encrypted. This is a similar issue to using scratchdir for staging
> query results
