Error in using Hadoop MapReduce in Eclipse

- by Shweta

When I executed a MapReduce program in Eclipse using Hadoop, I got the below error. It has to be some change in path, but I'm not able to figure it out. Any idea? 16:35:39 INFO mapred.JobClient: Task Id : attempt_201001151609_0001_m_000006_0, Status : FAILED java.io.FileNotFoundException: File C:/tmp/hadoop-Shwe/mapred/local/taskTracker/jobcache/job_201001151609_0001/attempt_201001151609_0001_m_000006_0/work/tmp does not exist. at org.apache.hadoop.fs.RawLocalFileSystem.getFileStatus(RawLocalFileSystem.java:361) at org.apache.hadoop.fs.FilterFileSystem.getFileStatus(FilterFileSystem.java:245) at org.apache.hadoop.mapred.TaskRunner.setupWorkDir(TaskRunner.java:519) at org.apache.hadoop.mapred.Child.main(Child.java:155)

How to classify NN/NNP/NNS obtained from POS tagged document as a product feature

- by Shweta .......

I'm planning to perform sentiment analysis on reviews of product features (collected from Amazon dataset). I have extracted review text from the dataset and performed POS tagging on that. I'm able to extract NN/NNP as well. But my doubt is how do I come to know that extracted words classify as features of the products? I know there are classifiers in nltk but I don't know how I should use it for my project. I'm assuming there are 2 ways of finding whether the extracted word is a product feature or not. One is to compare with a bag of words and find out if my word exists in that. Doubt: How do I create/get bag of words? Second way is to implement some kind of apriori algorithm to find out frequently occurring words as features. I would like to know which method is good and how to go about implementing it. Some pointers to available softwares or code snippets would be helpful! Thanks!
