HyukjinKwon opened a new pull request #26958: [SPARK-30128][SPARK-27627][SPARK-27990][SPARK-11412][FOLLOW-UP] Document/promote 'recursiveFileLookup' and 'pathGlobFilter' in file sources 'mergeSchema' in ORC URL: https://github.com/apache/spark/pull/26958 ### What changes were proposed in this pull request? This PR adds the options, 'recursiveFileLookup' and 'pathGlobFilter' in file sources 'mergeSchema' in ORC, into documentation. - `recursiveFileLookup` at file sources: https://github.com/apache/spark/pull/24830 ([SPARK-27627](https://issues.apache.org/jira/browse/SPARK-27627)) - `pathGlobFilter` at file sources: https://github.com/apache/spark/pull/24518 ([SPARK-27990](https://issues.apache.org/jira/browse/SPARK-27990)) - `mergeSchema` at ORC: https://github.com/apache/spark/pull/24043 ([SPARK-11412](https://issues.apache.org/jira/browse/SPARK-11412)) **Note that** `timeZone` option was not moved from `DataFrameReader.options` as I assume it will likely affect other datasources as well once DSv2 is complete. ### Why are the changes needed? To document available options in sources properly. ### Does this PR introduce any user-facing change? In PySpark, `pathGlobFilter` can be set via `DataFrameReader.(text|orc|parquet|json|csv)` and `DataStreamReader.(text|orc|parquet|json|csv)`. ### How was this patch tested? Manually built the doc and checked the output. Option setting in PySpark is rather a logical change. I manually tested one only: ```bash $ ls -al tmp ... -rw-r--r-- 1 hyukjin.kwon staff 3 Dec 20 12:19 aa -rw-r--r-- 1 hyukjin.kwon staff 3 Dec 20 12:19 ab -rw-r--r-- 1 hyukjin.kwon staff 3 Dec 20 12:19 ac -rw-r--r-- 1 hyukjin.kwon staff 3 Dec 20 12:19 cc ``` ```python >>> spark.read.text("tmp", pathGlobFilter="*c").show() ``` ``` +-----+ |value| +-----+ | ac| | cc| +-----+ ```
