SteNicholas opened a new pull request #13275: URL: https://github.com/apache/flink/pull/13275
## What is the purpose of the change *Method `configure()` of `HBaseRowInputFormat` and `HBaseRowDataInputFormat` is calling `connectToTable()`, which creates a connection to HBase that is not closed again. The connection is needed in the `createInputSplits` which is called before the openInputFormat method. The connection shoud be closed after closing table in method `closeInputFormat`, which sovled the leaking resources.* ## Brief change log - *Define `connection` which is opened in `configure()` and closed in `closeInputFormat()` in `AbstractTableInputFormat`.* ## Verifying this change ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn/Mesos, ZooKeeper: (yes / **no** / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
