> With the changes added as part of HIVE-20306, HiveMetaStoreClient now exposes new API "
> "getPartitionsWithSpecs" using which sentry can request specific information for partition.
> In simple words sentry could say fetch me the location information for the partitions in given table. Here is simple example on how it can be used.
