  • How do I control output files name and content of an Hadoop streaming job?

    - by Eran Kampf
    Is there a way to control the output filenames of an Hadoop Streaming job? Specifically I would like my job's output files content and name to be organized by the ket the reducer outputs - each file would only contain values for one key and its name would be the key. Update: Just found the answer - Using a Java class that derives from MultipleOutputFormat as the jobs output format allows control of the output file names. http://hadoop.apache.org/core/docs/current/api/org/apache/hadoop/mapred/lib/MultipleOutputFormat.htmlhttp://hadoop.apache.org/core/docs/current/api/org/apache/hadoop/mapred/lib/MultipleOutputFormat.html I havent seen any samples for this out there... Can anyone point out to an Hadoop Streaming sample that makes use of a custom output format Java class?

  • How do I determine the video file size on youtube in Java?

    - by user1753343
    I am using the youtube-API to gather different information about videos. The only missing attribute until now is size. The API itself doesn't provide any functionality. I googled, but didn't found any solution. Indirect way My next idea was to get the path to the video-file itself and make a get-request. In the response-headers I could check for the file size. So I searched for "video / download / youtube / java". Some time ago youtube used get_video_info but this doesn't work today. I also found an application called JavaYoutubeDownloader but it seems VERY complicated for just getting the file size and it doesn't work either (just prints finish, without downloading anything). So is there a way to get the filesize of a video on youtube by using Java? If not, what would be a practical solution for this problem (a list of video_ids exists)?

  • Excel + Web Data

    - by user348152
    I've spent hours scouring the net for anything to do with VBA calling data from the web in excel and nothing provides a tutorial on how to do so, only complicated examples un-related to what I want to do. I want to pull data from either a .html or .xml site, doesn't matter, via Excel and find specific points in that data. I can find specific points but don't know how to get the data or scroll through multiple lines. I've done this exact sort of thing in mIRC (sort of C code). http://eve-central.com/home/quicklook.html?typeid=438 http://api.eve-central.com/api/quicklook?typeid=438 Those are two examples, using roughly the same data I'd like to retrieve. It'd be FAR more specific with at most 100 or so different values. I'd like to be TAUGHT how to do it, not given the code to do it, or if you must explain each part with comments in-depth please. Thanks Nick

  • is there a limit on the number of times navigator.geolocation.getCurrentPostion can be called ?

    - by Raja
    Hi all, This is may not be a true programming question but deals with geolocation Api, hence hoping StackOverflow is the right place for this. I'm calling the navigator.geolocation.getCurrentPosition at every 3 seconds interval. After 10-15 tries the responses stop. So i'm wondering is there a limit on the number of calls being made, Or is it because i'm testing it with a desktop and hence instead of giving back the same response each time the API is waiting for a change of location. Anyone has any experiences to share ? Thanks

  • Best practice: How to persist simple data without a database in django?

    - by Infinity
    I'm building a website that doesn't require a database because a REST API "is the database". (Except you don't want to be putting site-specific things in there, since the API is used by mostly mobile clients) However there's a few things that normally would be put in a database, for example the "jobs" page. You have master list view, and the detail views for each job, and it should be easy to add new job entries. (not necessarily via a CMS, but that would be awesome) e.g. example.com/careers/ and example.com/careers/77/ I could just hardcode this stuff in templates, but that's no DRY- you have to update the master template and the detail template every time. What do you guys think? Maybe a YAML file? Or any better ideas? Thx

  • file_get_contents not displaying any data

    - by Lance
    I'm doing $info = file_get_contents('http://USERNAME:[email protected]/v2/sales?client_key=CLIENT_KEY'); $info returns nothing. However, when I put the URL into my browser, JSON appears. I tried using cURL without any luck. $data = array('client_key' => 'CLIENT_KEY'); $link = "http://api.appfigures.com/v2/sales"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $link); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, count($data)); curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); curl_setopt($ch, CURLOPT_USERPWD, "username:password"); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); $jsonData = curl_exec($ch); curl_close($ch); print_r($jsonData); Thanks

  • Manage build target variables in iphone project

    - by DougW
    We're transitioning to an automated build process for our iphone projects. These projects can be checked out by individual devs, in which case all the API URLs need to point to a certain path. There are also a variety of build environments, each with their own API root paths. I could probably add multiple, different build targets, and have each of them include a different URLs definition file, but this seems like a lot of upkeep and a bit overkill. Any best practices out there for swapping a few environmental variables for different build environments without much fuss?

  • Java REST Interface

    - by Vikram
    I have a PHP web application environment. I am using Slim Framework as REST interface for my application. My application front-end is written using Backbone.js and jQuery. There is a utility (.jar file) which when I use command line makes a remote call (I guess this is a Web Service) which returns me the data. how do I best incorporate this into my webapplication described on top? My application front end will have a Button that should make an AJAX call to the REST Interface and fetch the data as JSON. My approach: PHP-REST interface url is: /api/phprestapi.php exists Add a JAVA-REST interface at url: /api/javarestapi.java (Perhaps) to separate these two Existing Environment: LAMP Stack on Ubuntu How do I achieve this? What is the kind of effort involved? Thanks for your pointers

  • What encoding uses Flash Builder to send non english data to server?

    - by Ole Jak
    In my site I use Unicode... I hoped when I'll connect Flash Builder to my server (using Data - connect to HTTP ) It will work with my API sending Russian text as UTF-8 but instead it sends Þûõó ïúушúøý to my API and so to DB and so on instead of my favourite UTF-8 &#1056;&#1091;&#1089;&#1089;&#1082;&#1086;&#1077; &#1048;&#1084;&#1103; 2... So what encoding uses flash builder and How to make Flash Application send UTF-8 data to my server or some other readable format?

  • How do you deal with the more mundane parts of programming tasks?

    - by Uri
    My experience as a developer is that many projects or tickets are a mix of a short and focused very interesting task (e.g., designing some API or a platform to solve something) and a lot of repetitive and mundane tasks that cannot be automated (such as certain refactorings to use the API or platform, implementation of certain tests, some GUI handling, etc). I believe that this is the nature of our profession, unless we are high-level architects or managements and can delegate this work. The only item in my personal arsenal when dealing with these tasks is to devote some of my attention to radio or audiobooks (preferably not in English as I find it hard to concentrate on two "streams" of English at the same time). I maintain sufficient attention to carry the task and don't lose concentration as fast. I'm wondering how others cope with these and maintain concentration.

  • Unit testing task queues in AppEngine

    - by Swizec Teller
    For a very long time now I've been using task queues on AppEngine to schedule tasks, just the way I'm supposed to. But what I've always been wondering is how does one write tests for that? Until now I've simply made tests to make sure an error doesn't occur on the API that queues a task and then wrote the more proper tests for the API executing the task. However lately I've started feeling a bit unsatisfied by this and I'm searching for a way to actually test that the correct task has been added to the correct queue. Hopefully this can be done better than simply by deploying the code and hoping for the best. I'm using django-nonrel, if that has any bearing on the answer. To recap: How can a unit test be written to confirm tasks have been queued?

  • JAVA bytecode optimization

    - by Idob
    This is a basic question. I have code which shouldn't run on metadata beans. All metadata beans are located under metadata package. Now, I use reflection API to find out whether a class is located in the the metadata package. if (newEntity.getClass().getPackage().getName().contains("metadata")) I use this If in several places within this code. The question is: Should I do this once with: boolean isMetadata = false if (newEntity.getClass().getPackage().getName().contains("metadata")) { isMetadata = true; } C++ makes optimizations and knows that this code was already called and it won't call it again. Does JAVA makes optimization? I know reflection API is a beat heavy and I prefer not to lose expensive runtime.
