Binhua Hu updated RANGER-3968:
------------------------------
Description:
Rangeradmin's download and query interfaces depend on
RangerServicePoliciesCache to provide policy information.When a thread starts
to update the cache, other threads can only obtain the previous historical
information.In PolicyLoaderThread, the data is read from the database. If the
socket timeout is not set, the application will wait indefinitely before the
database returns the results.It will lead to failure to obtain the latest
policy information before restarting the application
As follows,
We create some new policies,the RangerAdmin policyVersion has updated,
!web policyVersion.png|width=621,height=302!
The policy version table relevant fields have also been updated,
!dataBase policyVersion.png|width=758,height=99!
But the plugin policy version is not updated
!plugin Json policyVersion2.png!
