> 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
