Traditionally word count example uses a line as input, so input can just be changed to {noformat} ( id uuid, line text, PRIMARY KEY (id)) {noformat} . Removed category, sub category, and title from input table and using UUID instead and a line to represent a line of text. Changed output schema to {noformat}(word text primary key, count int) {noformat} as suggested earlier. * Remove toString method and printing as it adds to unnecessary clutter in the mapper. * Remove the filter clauses as its not relevant to the word count example However I still see thrift interfaces in WordCountSetup class and runtime dependencies on cassandra in the bin folder. I didn't go into details, but can someone shed some light on the importance of having this. I think having clearly defined client API's/dependencies will be useful for the end user. > NPE in Hadoop Word count example > > > Key: CASSANDRA-6793 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6793 > Project: Cassandra > Issue Type: Bug > Components: Examples >Reporter: Chander S Pechetty >Assignee: Chander S Pechetty >Priority: Minor > Labels: hadoop > Attachments: trunk-6793-v2.txt, trunk-6793.txt > > > The partition keys requested in WordCount.java do not match the primary key > set up in the table output_words.
