> Key: SENTRY-2430
> URL: https://issues.apache.org/jira/browse/SENTRY-2430
> Project: Sentry
> Issue Type: Sub-task
> Components: Sentry
> Reporter: kalyan kumar kalvagadda
> Priority: Major
>
> 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.
>
>
>
>
> {code:java}
> GetPartitionsRequest request = new GetPartitionsRequest();
> GetPartitionsProjectSpec projectSpec = new GetPartitionsProjectSpec();
> projectSpec.setFieldList(Arrays.asList("sd.location"));
> GetPartitionsFilterSpec filter = new GetPartitionsFilterSpec();
> filter.setDbName("compdb");
> filter.setTblName("comptbl");
> request.setFilterSpec(filter);
> request.setProjectionSpec(projectSpec);
> GetPartitionsResponse response;
> try {
> response = client.getPartitionsWithSpecs(request);
> } catch (Exception ex) {
> ex.printStackTrace();
> LOG.error("Exception while retrieving partitions", ex);
> throw ex;
> }
> {code}
