how about _path? path1 looks weird...

or maybe we can create a class for this OutputWriter here.

now we never use the context and extension parameters?

Thanks - I'm going to merge this. I will address the doc and naming comment in the next pr in this series. |

@rxin This is a super minor but there are the same options to potentially rename in OrcOptions, JsonOptions, CSVOptions and TextFileFormat - TextFileFormat.scala#L71.
Also, I'd like to note, just in case, that the value in this is actually not the class name (it's something like SNAPPY and LZO) in case of ParquetOptions and OrcOptions whereas text-based ones are actual class names.

## What changes were proposed in this pull request? This patch adds a new "path" method on OutputWriter that returns the path of the file written by the OutputWriter. This is part of the necessary work to consolidate structured streaming and batch write paths. The batch write path has a nice feature that each data source can define the extension of the files, and allow Spark to specify the staging directory and the prefix for the files. However, in the streaming path we need to collect the list of files written, and there is no interface right now to do that. ## How was this patch tested? N/A - there is no behavior change and this should be covered by existing tests. Author: Reynold Xin <rxin@databricks.com> Closesapache#15580 from rxin/SPARK-18042.
