代码中存在一个错误,已经在FIWARE Lab的全局实例中修复。
我测试过这一点:
$ curl -X POST "http://computing.cosmos.lab.fiware.org:12000/tidoop/v1/user/myuser/jobs" -d '{"jar":"mrjars/hadoop-mapreduce-examples.jar","class_name":"wordcount","lib_jars":"mrjars/hadoop-mapreduce-examples.jar","input":"testdir","output":"outputdir"}' -H "Content-Type: application/json" -H "X-Auth-Token: mytoken"
{"success":"true","job_id": "job_1460639183882_0016"}
请在这种情况下观察,mrjars/hadoop-mapreduce-examples.jar
是hdfs:///user/myuser
下的相对路径。在此操作中始终使用相对路径。
$ curl -X GET "http://storage.cosmos.lab.fiware.org:14000/webhdfs/v1/user/myuser/mrjars?op=liststatus&user.name=myuser" -H "X-Auth-Token: mytoken"
{"FileStatuses":{"FileStatus":[{"pathSuffix":"hadoop-mapreduce-examples.jar","type":"FILE","length":270283,"owner":"myuser","group":"myuser","permission":"644","accessTime":1464702215233,"modificationTime":1464702215479,"blockSize":134217728,"replication":3}]}}
结果:
$ curl -X GET "http://storage.cosmos.lab.fiware.org:14000/webhdfs/v1/user/myuser/outputdir?op=liststatus&user.name=myuser" -H "X-Auth-Token: mytoken"
{"FileStatuses":{"FileStatus":[{"pathSuffix":"_SUCCESS","type":"FILE","length":0,"owner":"myuser","group":"myuser","permission":"644","accessTime":1464706333691,"modificationTime":1464706333706,"blockSize":134217728,"replication":3},{"pathSuffix":"part-r-00000","type":"FILE","length":128,"owner":"myuser","group":"myuser","permission":"644","accessTime":1464706333264,"modificationTime":1464706333460,"blockSize":134217728,"replication":3}]}}
我会上传修复到宇宙中回购尽快GitHub的。
这一次,我得到'{“success”:“false”,“error”:1}'。旧版和新版群集之间是否存在Hadoop版本差异,还是缺少某些内容? [Here](https://dl.dropboxusercontent.com/u/19150764/Cosmos_test.zip)是我用来测试的jar文件和示例输入。 – McMutton
