该项目从阿里的DataX 而来，经过了精简和改造，说明如下
删除了仅限于阿里内部的数据库，这些数据库在非阿里集团无法使用，因此直接删除，包括：
- ADS
- DRDS
- OCS
- ODPS
- OSS
- OTS
增加了部分插件，目前包括
- clickhousereader
- dbffilereader
- dbffilewrite
- hdfswriter 增加了对 Decimal 数据类型格式的支持
- hdfswriter 增加了对 Parquet 文件格式的支持
- hdfswrite 增加了目录覆盖模式
- hdfswriter 增加了更多的文件压缩格式支持
- hdfswriter 的临时目录位置改动为当前写入目录下的隐藏目录，解决了之前和写入目录平行导致的自动增加分区的问题
- hdfswriter 在覆盖模式下，改进了文件删除机制，减少了对应表查询为空的时间窗口
- hdfsreader 增加了对 Parquet 文件格式的支持
- hdfsreader 增加了更多的文件压缩格式支持
- hbasex11sqlwrite 增加了 Kerberos 支持
- 尽可能减少了本地jar包的依赖，转为从maven仓库获取
- 绝大部分依赖包升级到了最新稳定版本，减少了潜在漏洞
- 不同插件下的相同依赖包做了版本统一

git clone https://github.com/wgzhao/datax.git DataX
cd DataX
mvn clean package
mvn package assembly:single编译打包成功后，会在项目目录的target/datax 目录下创建一个 datax-<version>的 文件夹，其中 <version 表示版本。
job 子目录包含了大量的任务样本，其中 job.json 可以作为冒烟测试，执行如下
cd target/datax/datax-<version>
bin/datax.py job/job.json上述命令的输出大致如下：
