-----------------------------------------------
Summary: Avoid storing the path information for partitions in
default location
Key: SENTRY-2290
URL: https://issues.apache.org/jira/browse/SENTRY-2290
Project: Sentry
Issue Type: Sub-task
Components: Sentry
Affects Versions: 2.1.0
Reporter: kalyan kumar kalvagadda
Sentry can ignore the partitions entries which are located in default location
as they share the same permissions as the table. This will reduce the snapshot
size decreasing the time to persist the snapshot and also time to send the full
update to Namenode. This is important as the partition information has lion’s
share in a HMS Full snapshot. Same approach can be taken for tables as well but
the issue is that we need to re-construct the location based on the database
and table names while constructing the ACL for the table location. This may
increase the CPU overhead. With partitions we are safe to ignore the partitions
with default location as sentry doesn't support permissions on partitions.
