The variable "word" is defined in the scope of the for > loop so it cannot be used in collect method. > Possible solution could be to initialise the variable before the for and > assign a value inside the for. > Something like: > int count = 0; > String word; > for (String record : words) { > word = record; > count++; > } > out.collect(new Tuple2(word, count)); -- This message was sent by Atlassian JIRA (v6.3.4#6332)
