> Hive drop call fails in presence of TDE

> Issue Type: Bug
> Components: Security
> Affects Versions: 1.2.1, 2.0.0
> Reporter: Deepesh Khandelwal
> Assignee: Wei Zheng

> This should be committed to when Hive moves to Hadoop 2.8
> In Hadoop 2.8.0 TDE trash collection was fixed through HDFS-8831. This
> enables us to make drop table calls for Hive managed tables where Hive
> metastore warehouse directory is in encrypted zone. However even with the
> feature in HDFS, Hive drop table currently fail:
> {noformat}
> $ hdfs crypto -listZones
> /apps/hive/warehouse key2
> $ hdfs dfs -ls /apps/hive/warehouse
> Found 1 items
> drwxrwxrwt - hdfs hdfs 0 2016-09-01 02:54
> /apps/hive/warehouse/.Trash
> hive> create table abc(a string, b int);
> OK
> Time taken: 5.538 seconds
> hive> dfs -ls /apps/hive/warehouse;
> Found 2 items
> drwxrwxrwt - hdfs hdfs 0 2016-09-01 02:54
> /apps/hive/warehouse/.Trash
> drwxrwxrwx - deepesh hdfs 0 2016-09-01 17:15
> /apps/hive/warehouse/abc
> hive> drop table if exists abc;
> FAILED: Execution Error, return code 1 from
> org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:Unable to drop
> default.abc because it is in an encryption zone and trash is enabled. Use
> PURGE option to skip trash.)
> {noformat}
> The problem lies here:
> {code:title=metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java}
> private void checkTrashPurgeCombination(Path pathToData, String objectName,
> boolean ifPurge)
> ...
> if (trashEnabled) {
> try {
> HadoopShims.HdfsEncryptionShim shim =
>
> ShimLoader.getHadoopShims().createHdfsEncryptionShim(FileSystem.get(hiveConf),
> hiveConf);
> if (shim.isPathEncrypted(pathToData)) {
> throw new MetaException("Unable to drop " + objectName + "
> because it is in an encryption zone" +
> " and trash is enabled. Use PURGE option to skip trash.");
> }
> } catch (IOException ex) {
> MetaException e = new MetaException(ex.getMessage());
> e.initCause(ex);
> throw e;
> }
> }
> {code}
> As we can see that we are making an assumption that delete wouldn't be
> successful in encrypted zone. We need to modify this logic.
