GitHub user c-sahuja opened a pull request:
https://github.com/apache/spark/pull/16185
Update Spark documentation to provide information on how to create External
Table
## What changes were proposed in this pull request?
Although, currently, the saveAsTable does not provide an API to save the
table as an external table from a DataFrame, we can achieve this functionality
by using options on DataFrameWriter where the key for the map is the String:
"path" and the value is another String which is the location of the external
table itself. This can be provided before the call to saveAsTable is performed.
## How was this patch tested?
Documentation was reviewed for formatting and content after the push was
performed on the branch.
