ferenc-csaky opened a new pull request, #23293:
URL: https://github.com/apache/flink/pull/23293
## What is the purpose of the change
Try to create dirs that does not exists when opening file catalog store. If
an error is thrown in case the given path not exists, SQL client will fail to
start, also SQL gateway won't operate, cause even basic API calls will fail.
It makes sense to at least try creating any missing folders, which can
probably help allow some annoying errors and restart rounds.
## Brief change log
Add `FileSystem.mkdirs(...)` to `FileCatalogstore.open()` to try creating
dirs the given path does not exist.
## Verifying this change
Added unit test to verify a failing scenario. Every other existing unit test
will now create the store root folder.
