You can access task values in downstream tasks in the same job run. A move is a copy followed by a delete, even for moves within filesystems. To display help for this command, run dbutils.jobs.taskValues.help("get"). As in a Python IDE, such as PyCharm, you can compose your markdown files and view their rendering in a side-by-side panel, so in a notebook. Therefore, by default the Python environment for each notebook is isolated by using a separate Python executable that is created when the notebook is attached to and inherits the default Python environment on the cluster. Therefore, we recommend that you install libraries and reset the notebook state in the first notebook cell. This example runs a notebook named My Other Notebook in the same location as the calling notebook. If you dont have Databricks Unified Analytics Platform yet, try it out here.
