copied!<p>I have setup Hadoop1.2.1 in windows with CYGWIN installed. I have started sshd service. Also started namenode, datanode, mapreduce (job tracker, task tracker). I am able to see the namenode, datanode and mapreduce running status through the following URLs.</p> <p>When i try connecting the hadoop through eclipse, i am able to.Though i was able to connect hadoop from eclipse, i was not seeing any folders on opening DFS locations. Its displaying as (0) (refer Pic #1 , <img src="https://i.stack.imgur.com/5a3bf.png" alt="enter image description here"> which i guess no directories/files available. The same i checked with namenode storage (refer Pic #2)</p> <p>Even when i try creating a directory through CYGWIN terminal (refer Pic #4), i was not able to see it in DFS locations in eclipse environment. <img src="https://i.stack.imgur.com/VQ1d3.png" alt="enter image description here"></p> <p>That being said, i tried with WordCount example, by setting the input path and output path as follows, // specify input and output dirs</p> <pre><code>FileInputFormat.addInputPath(conf, new Path("Input")); FileOutputFormat.setOutputPath(conf, new Path("Output")); </code></pre> <p>When i run that in HDFS location from eclipse, i was getting the following exception</p> <p><strong>13/10/30 06:52:44 ERROR security.UserGroupInformation: PriviledgedActionException as:Administrator cause:org.apache.hadoop.mapred.InvalidInputException: Input path does not exist: hdfs://localhost:47110/user/Administrator/Input org.apache.hadoop.mapred.InvalidInputException: Input path does not exist: hdfs://localhost:47110/user/Administrator/Input</strong></p> <p>Questions: Why i am not able to see the directory that i created through CYGWIN terminal and any folders for that matter?<br> What does "hdfs://localhost:47110" point to?<br> Am i getting the above exception since it dont see the directory in datanode? What is the input path should i set?</p> <p>Please advice me on this.</p> <p>Thanks in advance.</p>
