[GitHub] [spark] MaxGekk opened a new pull request #29675: [SPARK-32815][ML][3.0] Fix LibSVM data source loading error on file paths with glob metacharacters
MaxGekk opened a new pull request #29675:
URL: https://github.com/apache/spark/pull/29675
### What changes were proposed in this pull request?
In the PR, I propose to fix an issue with LibSVM datasource when both of the following are true:
* no user specified schema
* some file paths contain escaped glob metacharacters, such as `[``]`, `{``}`, `*` etc.
The fix is a backport of https://github.com/apache/spark/pull/29670, and it is based on another bug fix for CSV/JSON datasources https://github.com/apache/spark/pull/29659.
### Why are the changes needed?
To fix the issue when the follow two queries try to read from paths `[abc]`:
```scala
spark.read.format("libsvm").load("""/tmp/\[abc\].csv""").show
```
but would end up hitting an exception:
```
Path does not exist: file:/private/var/folders/p3/dfs6mf655d7fnjrsjvldh0tc0000gn/T/spark-6ef0ae5e-ff9f-4c4f-9ff4-0db3ee1f6a82/[abc]/part-00000-26406ab9-4e56-45fd-a25a-491c18a05e76-c000.libsvm;
