Implement row level security in Impala

Hi,

 

I  want to impliment Row-Level security in Impala and Hive. Can anyone suggest best posible options available to do that.I am using Cloudera Managed cluster ( 5.6 ) .I am already using Sentry but it has only column level security available.

 

I want to restrict centain roles to access particular rows alone.Thanks in advance

 

Regards,

Re: Implement row level security in Impala

Impala/Hive currently do not have native support for this feature, but as a workaround you can create a view with a filter that expresses which rows are accessible, and then grant/deny access to the view.

Re: Implement row level security in Impala

I read some documents about Record Service which can do row level restriction.Is there any performance bottleneck if we use this product ?
