"To check if a specific keyword exists in a large text file using Apache Spark, you can use the filter() transformation with regex. Here's an example: nn val textFile = spark.textFile("path/to/your/file")n val containsKeyword = textFile.filter(line => line.matches("[w]+"+keyword+"[w]+"))n val result = containsKeyword.count()n if (result > 0) {n println("Keyword found!")n } else {n println("Keyword not found.")n }n"n
