There was a bug in the code, already fixed in the global instance of FIWARE Lab.
I've tested this:
$ 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"}
Please observe in this case, mrjars/hadoop-mapreduce-examples.jar
is a relative path under hdfs:///user/myuser
. Always use relative paths with this opeartion.
$ 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}]}}
The result:
$ 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}]}}
I'll upload the fix to the Cosmos repo in GitHub ASAP.
