Review request for sentry, Lenni Kuff and Sravya Tirukkovalur.


Repository: sentry


Description
-------

Currently, when get the metadata from hive, eg, "show tables", "show 
databases". Sentry will filter the result and output the authorized entities. 
There will be many RPC calls when filtering the result. The related code is in 
HiveAuthzBinding, for example, in filterShowTables:

......
for (String tableName : queryResult) {
  ......
  hiveAuthzBinding.authorize(operation, tableMetaDataPrivilege, subject, 
inputHierarchy,
            outputHierarchy, providedPrivileges);
  ......
}
......

hiveAuthzBinding.authorize will get the privileges from sentry service, if 
there are many tables in the hive, the filtering process will spend much time. 
Considering sentry also need to filter the column, HiveAuthzBinding should be 
improved to reduce the number of rpc calls when doing the filter.
