Greetings! Hi, Am trying to modify the WordCount.java mentioned at Example: WordCount v1.0<http://hadoop.apache.org/core/docs/current/mapred_tutorial.html#Example%3A+WordCount+v1.0>at http://hadoop.apache.org/core/docs/current/mapred_tutorial.html Would like to have output the following way,
FileOne word1 itsCount FileOne word2 itsCount ..(and so on) FileTwo word1 itsCount FileTwo wordx its Count .. FileThree word1 its Count .. Am trying to do following changes to the code of WordCount.java 1) private Text filename = new Text(); // Added this to Map class .Not sure if I would have access to filename here. 2) (line 18)OutputCollector<Text, Text, IntWritable> output // Changed the argument in the map() function to have another Text field. 3) (line 23) output.collect(filename, word , one); // Trying to change the output format as 'filename word count' Am not sure what other changes are to be affected to achieve the required output. filename is not available to the map method. My requirement is to go through all the data available in hdfs and prepare an index file with < filename word count> format. Could you please throw light on how I can achieve this. Thankyou Srilatha
