Subject [jira] [Commented] (HIVE-10658) ACID operation expose encrypted data
Date Sat, 09 May 2015 00:44:59 GMT


Eugene Koifman commented on HIVE-10658:

for example, insert into T values(1),(2)
This is done by creating a temp table with 2 rows and then running insert into T select *
from values__tmp__table__1.
(Actually, T doesn't need to be ACID.)

Temp tables automatically create the data file under scratchdir.  (at least this is what I've
been told Do your changes handle temp tables as well?)

> 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
