Work Description: baifachuan commented on pull request #2987:
URL: https://github.com/apache/hive/pull/2987#issuecomment-1031046556
I fixed the bug with check the hive storage path, if it is a ROOT path throw
an exception, broken the create table.
```
DEBUG : Shutting down query CREATE EXTERNAL TABLE `fcbai1`(
`inv_item_sk` int,
`inv_warehouse_sk` int,
`inv_quantity_on_hand` int)
PARTITIONED BY (
`inv_date_sk` int) STORED AS ORC
LOCATION
'hdfs://127.0.0.1:8020/'
Error: Error while processing statement: FAILED: Execution Error, return
code 1 from org.apache.hadoop.hive.ql.exec.DDLTask.
InvalidObjectException(message:fcbai1 location must not be root path)
(state=08S01,code=1)
```
Ensure that creating tables and dropping tables behave the same.

> I create the external hive table using this command:
>
> {code:java}
> CREATE EXTERNAL TABLE `fcbai`(
> `inv_item_sk` int,
> `inv_warehouse_sk` int,
> `inv_quantity_on_hand` int)
> PARTITIONED BY (
> `inv_date_sk` int) STORED AS ORC
> LOCATION
> 'hdfs://emr-master-1:8020/';
> {code}
>
> The table was created successfully, but when I drop the table throw the NPE:
>
> {code:java}
> Error: Error while processing statement: FAILED: Execution Error, return code
> 1 from org.apache.hadoop.hive.ql.exec.DDLTask.
> MetaException(message:java.lang.NullPointerException)
> (state=08S01,code=1){code}
>
> The same bug can reproduction on the other object storage file system, such
> as S3 or TOS:
> {code:java}
> CREATE EXTERNAL TABLE `fcbai`(
> `inv_item_sk` int,
> `inv_warehouse_sk` int,
> `inv_quantity_on_hand` int)
> PARTITIONED BY (
> `inv_date_sk` int) STORED AS ORC
> LOCATION
> 's3a://bucketname/'; // 'tos://bucketname/'{code}
>
> I see the source code found:
> common/src/java/org/apache/hadoop/hive/common/FileUtils.java
> {code:java}
> // check if sticky bit is set on the parent dir
> FileStatus parStatus = fs.getFileStatus(path.getParent());
> if (!shims.hasStickyBit(parStatus.getPermission())) {
> // no sticky bit, so write permission on parent dir is sufficient
> // no further checks needed
> return;
> }{code}
>
> because I set the table location to HDFS root path
> (hdfs://emr-master-1:8020/), so the path.getParent() function will be return
> null cause the NPE.
> I think have four solutions to fix the bug:
> # modify the create table function, if the location is root dir return
> create table fail.
> # modify the FileUtils.checkDeletePermission function, check the
> path.getParent(), if it is null, the function return, drop successfully.
> # modify the RangerHiveAuthorizer.checkPrivileges function of the hive
> ranger plugin(in ranger rep), if the location is root dir return create table
> fail.
> # modify the HDFS Path object, if the URI is root dir, path.getParent()
> return not null.
> I recommend the first or second method, any suggestion for me? thx.
