---------------------------------
Summary: The plugin cannot download the latest policy
Key: RANGER-3968
URL: https://issues.apache.org/jira/browse/RANGER-3968
Project: Ranger
Issue Type: Improvement
Components: admin
Affects Versions: 2.2.0, 1.2.0
Reporter: Binhua Hu
Assignee: Binhua Hu
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
