--------------------------------------
Summary: Increment service-specific policy and tag versions after
update transaction is committed
Key: RANGER-2186
URL: https://issues.apache.org/jira/browse/RANGER-2186
Project: Ranger
Issue Type: Bug
Components: Ranger
Affects Versions: master
Reporter: Abhay Kulkarni
Assignee: Abhay Kulkarni
Fix For: master
Policy updates to different policies within a service, when successful, update
the service's policy version. If the update transactions are concurrent, and
executed on different ranger-admin servers (in HA configuration), then it is
possible that policy-version of the transaction that commits later overwrites
policy-version of earlier transaction, effectively losing track of the first
change.
If policy-version is updated after update to policy is committed, then the
window of such loss is greatly reduced.
Similar considerations apply for tag updates.
