Bugs: RANGER-4123
    https://issues.apache.org/jira/browse/RANGER-4123


Repository: ranger


Description
-------

**Problem Statement:**
During the ranger upgrade process, Java patch J10019 updates the policy and 
policy json is also updated in policy_text column of each row. However policy 
update entry is not being captured in x_data_hist. whenever we click on policy 
id link of access audit page the /plugins/policies/eventTime API is called 
along with corresponding policy id and version. if x_data_hist table does 
contain such entry then API request fails with error message "No policy found 
for given version"

**Proposed solution:** The proposed changes shall create an entry in 
x_data_hist table for each policy which is being updated.

Testing
-------

Without this patch x_data_hist was not having any entry after the execution of 
patch J10019. 
However after this change the x_data_hist table is populated and API call is 
working.


Thanks,

Pradeep Agrawal
