Subject [jira] [Commented] (HIVE-10658) Insert with values clause may expose data that should be encrypted

Sergio Peña commented on HIVE-10658:
------------------------------------

Hi,

Could you use the method 'isPathEncrypted' that is already part of SemanticAnalyzer class?
This will get the hdfs encryption shim from SessionState. 
Also, what if the encryption zone is read-only?

Take a look at the 'getStrongestEncryptedTablePath(QB qb)' method. This checks for read-only
tables, and compares key strengths between encryption zones.

> Insert into T values() operation uses temporary table.
> 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
