We use Impala and Hue to query the Kudu tables. We have now installed Sentry for access control, using which we are now able to restrict a users access to a particular column of the table. I wanted to know If we can put restriction to access a particular range partition of the table. For example if Table T1 has five columns say c1,c2, c3, c4 and c5 and 3 Range partitions p1, p2 and p3. As of now using sentry I am able to restrict access only to columns c1, c2 and c5. I also wanted to know if I can restrict access of user to only partition p1.
As of Kudu v1.10 it's not possible to restrict access on a per-partition (i.e. per-tablet) basis.
