An error occurred in the API call. Source API type: <apiType>. Error code: <errorCode>. This can sometimes happen when you’ve reached a API limit. If you haven’t exceeded your API limit, try re-running the connector. If the issue persists, please file a ticket. DC_UNSUPPORTED_...
For example, to turn on debug HTTP headers:from databricks.sdk import WorkspaceClient w = WorkspaceClient(debug_headers=True) # Now call the Databricks workspace APIs as desired...Long-running operationsWhen you invoke a long-running operation, the SDK provides a high-level API to trigger ...
The functions above are exposed in the Scala API only, at the moment, as there is no separate Python package forspark-xml. They can be accessed from Pyspark by manually declaring some helper functions that call into the JVM-based API from Python. Example: ...
operate on files, the results are stored in the directory /databricks/driver. Before you load the file using the Spark API, you can move the file to DBFS usingDatabricks Utilities. The last block of code in this section of the script will list the files stored in the databricks/d...

Another, more subtle, example of a dangling RDD reference is this: consider a notebook cell with a single unpersist call: myRdd.unpersist() RDD.unpersist() returns a reference to the RDD being unpersisted. The last value in a notebook cell is automatically assigned...
