[SPARK-11905](https://issues.apache.org/jira/browse/SPARK-11905) added support for `persist`/`cache` for `Dataset`. However, there is no user-facing API to check if a `Dataset` is cached and if so what the storage level is. This PR adds `getStorageLevel` to `Dataset`, analogous to `RDD.getStorageLevel`. Updated `DatasetCacheSuite`. Author: Nick Pentreath <nickp@za.ibm.com> Closes #13780 from MLnick/ds-storagelevel. Signed-off-by: Michael Armbrust <michael@databricks.com> |
