In this PySpark installation article, you have learned the step-by-step installation of PySpark. Now access from your favorite web browser to access Spark Web UI to monitor your jobs. For more examples on PySpark refer to PySpark Tutorial with Examples. Enter the following commands in the PySpark shell in the same order.ĭata = ![]() Let’s create a PySpark DataFrame with some sample data to validate the installation. If you are interested in the module, please let me know so I have an idea of the amount of interested people.Note that it displays Spark and Python versions to the terminal. I also want to get my app to clean up the installer, if it was used successfully, a bit more design is required. However having the app on the machine verify the code signature of the installer will ensure the highest level of security (IMHO). In the future I intend to update it to verify the code signature of the package (at the moment it verifies a hash of the file against the fileSignature (but that can be hacked if someone figures out which hashing method I’m using and the salting string. Using the Apple installer, will locate and replace the current version with the newer version, asking admin credentials if required. Once it’s downloaded, if launches the update file (I’m using the Apple Installer package for updates) and quits the current application. When the user choose to update, it then uses the same HTTPSocket to download the update file to it’s Application Support folder. It then displays all the available update information, but only offers the option to download the latest available update. When it’s time to check, my app uses a HTTPSocket to download the update file, then processes it into an array of objects and scans each object to see if it’s newer than the current version and meets the architecture, minOS requirements, then it will add it to the list of available updates. 8 MBįileSiganture - a hash of the update file.Įach file may contain multiple versions, with the latest always appearing at the top. MinOS - contains the required OS for this update.Īrchitecture - the architectures it will run on.ĭisplayVersion - Human readable version i.e 3.0 Beta 1ĭownloadSize - a human readable string i.e. ReleaseDate - the date the update was released. Signature - which a hash of the entire file contents.īeginUpdate - which is used to signal update information follows.īuild - which ties into the non-release version (so it's a simple comparison). ![]() I start with a version simple update format, a sample file can be found here. If you are interested in the module, please let me know so I have an idea of the amount of interested Perez:Ĭorrect, the code I’ve written is specifically for OS X, maybe if I explain how it works, Joris can use that information to provide a full x-plat kit (in native Xojo code). ![]() I’ll be officially announcing the module as soon as it is ready. Initially the module will be OS X-only (10.7 and up), but I do have plans for extending it’s functionality to Windows and maybe even Linux. The module will handle the rest, from checking for updates to installing and launching the updated application. ![]() No need to manually sign anything or create AppCast files! All you need to do manually is create a HTML file containing the release notes (a sample file will be included) and upload it - together with the generated update package - to your web server. The Build Steps initialize the auto-update system and create an update package containing a signed update archive (using a public/private DSA key pair, which is also automatically generated by the Build Step) and a feed file (like the AppCast file you would use with Sparkle). All you need to do is add two Build Steps and include the module in your project. One of the unique features of the module will be the way you set everything up. Additionally, it will include functionality for showing notifications to the user (e.g. I’m actually working on a very easy to use module (100% native Xojo, no need for plugins), that includes similar functionality to Sparkle.
