生成parcel

# 需要在目标文件夹内新建meta文件，并在meta中新建文件parcel.json，文件内容需要自己参考资料填写
# 验证文件
java -jar cm_ext/validator/target/validator.jar -p HELLO-1.0/meta/parcel.json
# 验证目录
java -jar cm_ext/validator/target/validator.jar -d HELLO-1.0
# 打包parcel
tar zcvf HELLO-1.0-el6.parcel HELLO-1.0 --owner=root --group=root
# 验证
java -jar cm_ext/validator/target/validator.jar -f HELLO-1.0-el6.parcel

对外提供http的parcel服务

# 生成manifest.json
python cm_ext/make_manifest/make_manifest.py /data/root
# 提供http服务
python -m SimpleHTTPServer 10001

配置cm的parcel

添加上述http地址，即可分发parcel

生成CSD

# 新建目录，内部结构为
├── descriptor
│   └── service.sdl
└── scripts
    └── control.sh
# 文件内容需要自己参考资料填写
#验证
java -jar cm_ext/validator/target/validator.jar -s csd/HELLO-1.0/descriptor/service.sdl
# 打包
jar -cvf HELLO-1.0.jar *
# 复制到csd目录
~~~cp HELLO-1.0.jar /opt/cloudera/csd/
### 重启cm服务即可生效
### 示例
HELLO-1.0/meta/parcel.json
~~~ json
