word-count

I need some help on figuring out why my job failed. I built a single node cluster just to try it out. I followed the example here . Everything seems to be working correctly. I formatted the namenode and am able to connect to the jobtracker, datanode, and namenode via the web interface. I am able to start and stop all the hadoop services. However, when I try to run the wordcount example, I get this: Error initializing attempt_201105161023_0002_m_000011_0: java.io.IOException: Exception reading file:/app/hadoop/tmp/mapred/local/ttprivate/taskTracker/hadoop/jobcache/job_201105161023_0002/jobToken

I need to create a list of words used in all cells in column A, with a count of occurrence for each word on the list. So far, I've been able to create the list of words. (by searching the forum.) The list of words is generated in column B, can anyone help me with the code so it also generate the count of occurrence in column C? Thank you! Sub Sample() Dim varValues As Variant Dim strAllValues As String Dim i As Long Dim d As Object 'Create empty Dictionary Set d = CreateObject("Scripting.Dictionary") 'Create String With all possible Values strAllValues = Join(Application.Transpose(Range("A1",

I would like to do a function which can count the unique words. For example: "I like to program something useful. And I like to eat. Eat ice-cream now." In this case, each unique words: I occurs 2 like occurs 2 ... I will ignore the case later on. Please help EDIT: I have finished write the functions. It works perfectly. Thanks for all the help. Very much appreciated. Sounds like you want to use an std::map with a key string and data of int. If an item doesn't exist in the map already you add it with an int value of 1. If the item does exist in the map already you simply add 1 to its

After trying to figure how to have an effective word counter of a string, I know about the existing function that PHP has str_word_count but unfortunately it doesn't do what I need it to do because I will need to count the number of words that includes English, Chinese, Japanese and other accented characters. However str_word_count fails to count the number of words unless you add the characters in the third argument but this is insane , it could mean I have to add every single character in the Chinese, Japanese, accented characters (etc) language but this is not what I need. Tests: str_word

I am a beginner in hadoop using the hadoop's beginners guide book as a tutorial. I am using a mac osx 10.9.2 and hadoop version 1.2.1 I have set all the appropriate class path, when I call echo $PATH in terminal: Here is the result I get: /Library/Frameworks/Python.framework/Versions/2.7/bin:/Users/oladotunopasina/hadoop-1.2.1/hadoop-core-1.2.1.jar:/Users/oladotunopasina/hadoop-1.2.1/bin:/usr/share/grails/bin:/usr/share/groovy/bin:/Users/oladotunopasina/.rvm/gems/ruby-2.1.1/bin:/Users/oladotunopasina/.rvm/gems/ruby-2.1.1@global/bin:/Users/oladotunopasina/.rvm/rubies/ruby-2.1.1/bin:/usr/local

I am trying to get a phrase count from a text file but so far I am only able to obtain a word count (see below). I need to extend this logic to count the number of times a two-word phrase appears in the text file. Phrases can be defined/grouped by using logic from NLTK from my understanding. I believe the collections function is what I need to obtain the desired result, but I'm not sure how to go about implementing it from reading the NLTK documentation. Any tips/help would be greatly appreciated. import re import string frequency = {} document_text = open('Words.txt', 'r') text_string =

I am trying to run word count example on Eclipse . Generally when we click on "run on hadoop" option in eclipse we get a new window asking to select server location. But, now it is directly running the program without asking me to choose an existing server from list below. I think because of this I am getting the following exception: 13/04/21 08:46:31 ERROR security.UserGroupInformation: PriviledgedActionException as:hduser1 cause:org.apache.hadoop.mapred.InvalidInputException: Input path does not exist: file:/home/hduser1/gutenbergIP/pg4300.txt Exception in thread "main" org.apache.hadoop
