This unique key is known as the task values key. Moves a file or directory, possibly across filesystems. You cannot use Run selected text on cells that have multiple output tabs (that is, cells where you have defined a data profile or visualization). databricks-cli is a python package that allows users to connect and interact with DBFS. This is useful when you want to quickly iterate on code and queries. This example restarts the Python process for the current notebook session. For example, Utils and RFRModel, along with other classes, are defined in auxiliary notebooks, cls/import_classes. The file system utility allows you to access What is the Databricks File System (DBFS)?, making it easier to use Azure Databricks as a file system. Databricks Utilities (dbutils) make it easy to perform powerful combinations of tasks. Databricks is a platform to run (mainly) Apache Spark jobs. Since clusters are ephemeral, any packages installed will disappear once the cluster is shut down. These magic commands are usually prefixed by a "%" character. To display help for this command, run dbutils.library.help("restartPython"). These values are called task values. This example creates the directory structure /parent/child/grandchild within /tmp.
