Hello, I'm trying to find a way how to run hadoop MapReduce app from another machine. For instance I have *.jar file with MapReduce app it works ok when I run it from command line for instance using this command: "hadoop jar /usr/joe/wordcount.jar org.myorg.WordCount /usr/joe/wordcount/input /usr/joe/wordcount/output" But in situation when I have another server (simple web app) where user can upload jar file, specify configuration for the MapReduce app and so on. And this server should interact with hadoop server. I mean somehow to upload this jar file to the hadoop server and run it with attributes.
So, right now I see only one way of how to do this, it's upload jar file to the hadoop server and run remotely command: "hadoop jar /usr/joe/wordcount.jar org.myorg.WordCount /usr/joe/wordcount/input /usr/joe/wordcount/output". So may be hadoop has spatial API for doing this kind of tasks remotely? -- View this message in context: http://old.nabble.com/Run-hadoop-Map-Reduce-app-from-another-machine-tp32595264p32595264.html Sent from the Hadoop core-user mailing list archive at Nabble.com.
