So what I did was add this little snippet in main method of HelloStorm. Apache POI is a Java library for working with the various file formats based on the Office Open XML standards (OOXML) and Microsofts OLE 2 Compound Document format (OLE2). If you run the above program as-is, it might not show up on the storm UI. StormExecutable jarOption pathToYourJarFile theClassContainingYourMainFile commandlineArguments The above command is basically just this.If you want to pass commandline arguments to your program, add it at the end: storm jar /Users/nav/myworkspace/StormTrial/build/libs/HelloStorm2-0.0.1-SNAPSHOT.jar test.txt Mvn package - this will create a jar of the project.Ĭd /Users/nav/programming/apache-storm-1.0.1/binĥ.
Apache word program how to#
I see that many newbies like me visit this site for reference and have been asking about how to run this program. Thanks Sunil for this basic and yet very helpful project.
Now execute the HelloStorm.java and pass it name of the text file that you want to count words in. The HelloStorm.java is the place where everything gets tied together, it specifies how the Spouts and Bolts are related to each other. cleanup(): This method would be called at the end and we are using it to print all the words with their frequency. execute(): This method takes care of building/maintaining a HashMap for counting the frequency of the words. declareOutputFields(): This method is empty because we dont want to return any tuples for further processing. prepare(): In this method i am creating a HashMap that would be used for maintaining list of words to their frequency count. Next create the WordCounterBolt.java which implements the IRichBolt interface like this execute(): This is the method where you implement business logic of your bolt, in this case i am splitting the input line into words and passing them back to Storm for further processing. declareOutputFields(): This method is similar to declareOutputFields() method in LineReaderSpout, it declares that it is going to return word tuple for further processing.

prepare(): This method is similar to open() method in LineReaderSpout, it allows you to initialize your code and get access to OutputCollector object for passing output back to Storm. Next create WordSpitterBolt.java which implements WordSpitterBolt interface like this declareOutputFields(): This method declares that LineReaderSpout is going to emit line tuple. nextTuple(): This method would allow you to pass one tuple to storm for processing at a time, in this method i am just reading one line from file and pass it to tuple. You read value of inputFile configuration variable and read that file open(): This method would get called at the start and will give you context information. The LineReaderSpout code has three important methods Apache word program download#
Click on the DOWNLOAD button on the sidebar to go directly to the Apache. Now create LineReaderSpout.java like this, implement IRichSpout interface You can do all your word processing, presenting, and spreadsheet building with. Apache OpenOffice For Windows is a free, Open Source MS Office alternative with a Word compatible word processor, a complete Excel compatible spreadsheet.
