[doris-thirdparty] branch libhdfs3 updated: [Enhancement] Add HDFS TDE/KMS functions. Now only support HDFS3. (#22)
This is an automated email from the ASF dual-hosted git repository.
morningman pushed a commit to branch libhdfs3
in repository https://gitbox.apache.org/repos/asf/doris-thirdparty.git
The following commit(s) were added to refs/heads/libhdfs3 by this push:
new cc8b351 [Enhancement] Add HDFS TDE/KMS functions. Now only support HDFS3. (#22)
cc8b351 is described below
commit cc8b3519cf7210d0df1d53e2199511f435fa962d
Author: Qi Chen <ka...@gmail.com>
AuthorDate: Tue Jan 10 15:00:40 2023 +0800
[Enhancement] Add HDFS TDE/KMS functions. Now only support HDFS3. (#22)
## Test Steps with Doris
1. Compile this third-partiry lib with doris.
2. Setup hadoop3 and hive3 env and kms-related env.
3. Start hdfs server, kms server, hive metastore server.
4. Create hive warehouse root dir and create encryption zone as this root dir path on the HDFS.
```
// hive warehouse root dir
hadoop fs -mkdir /data/hive
// create key
hadoop key create key1
// create encryption zone as hive warehouse root dir path.
hdfs crypto -createZone -keyName key1 -path /data/hive
```
5. Create hive tables. And you can check the raw encrypted files.
```
// can check raw encrypted file
hdfs dfs -cat /.reserved/raw/data/hive/*
```
6. Add kms settings in`be/conf/hdfs-site.xml` or `CREATE RESOURCE` DDL.
`dfs.encryption.key.provider.uri: 'kms://http@localhost:9600/kms'`
7. Use multi-catalog to read hive tables. The hive tables in encryption zone can be queried.
