从stream流读取数据并打印到控制台
1）查看配置模板
[jason@hadoop102 bin]$ python datax.py -r streamreader -w streamwriter DataX (DATAX-OPENSOURCE-3.0), From Alibaba ! Copyright (C) 2010-2017, Alibaba Group. All Rights Reserved. Please refer to the streamreader document: https://github.com/alibaba/DataX/blob/master/streamreader/doc/streamreader.md Please refer to the streamwriter document: https://github.com/alibaba/DataX/blob/master/streamwriter/doc/streamwriter.md Please save the following configuration as a json file and use python {DATAX_HOME}/bin/datax.py {JSON_FILE_NAME}.json to run the job. { "job": { "content": [ { "reader": { "name": "streamreader", "parameter": { "column": [], "sliceRecordCount": "" } }, "writer": { "name": "streamwriter", "parameter": { "encoding": "", "print": true } } } ], "setting": { "speed": { "channel": "" } } } }
2）根据模板编写配置文件
[jason@hadoop102 job]$ vim stream2stream.json
填写以下内容：
{ "job": { "content": [ { "reader": { "name": "streamreader", "parameter": { "sliceRecordCount": 10, "column": [ { "type": "long", "value": "10" }, { "type": "string", "value": "hello，DataX" } ] } }, "writer": { "name": "streamwriter", "parameter": { "encoding": "UTF-8", "print": true } } } ], "setting": { "speed": { "channel": 1 } } } }
3）运行
[jason@hadoop102 job]$ /opt/module/datax/bin/datax.py /opt/module/datax/job/stream2stream.json
