Info In addition to the magics added by the PySpark kernel, you can also use the built-in IPython magics, including %%sh. Das Magic-Wort sollte das erste Wort in der Zelle sein. Smaller cluster size as data is stored remotely? Simplified version management - Azure HDInsight manages the version of Hadoop eco-system components and keeps them up to date. Microsoft will work with the open-source community to contribute the relevant changes back to the Apache project itself. Additional projects will be included in the distribution based on feedback from customers, partners, and the open-source community.
Sie müssen also keine Anweisungen wie die folgenden ausführen, um die Kontexte festzulegen:So, you don't have to run statements like the following to set the contexts: Stattdessen können Sie in Ihrer Anwendung direkt die vordefinierten Kontexte verwenden.Instead, you can directly use the preset contexts in your application. In der folgenden Tabelle sind die verschiedenen über den Kernel verfügbaren Magics aufgeführt.
