zhangxinyao88 opened a new pull request, #59075: URL: https://github.com/apache/spark/pull/59075
### What changes were proposed in this pull request? Close the JDBC connection created for a DSv2 truncate operation in `JDBCWriteBuilder`. Add a regression test that verifies every JDBC connection created during the write is closed. ### Why are the changes needed? `JDBCWriteBuilder` creates a driver-side connection for truncate, while `JdbcUtils.truncateTable` closes only its statement. The connection otherwise remains open. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Added a `JDBCV2Suite` regression test for `DataFrameWriterV2` truncate connection closure. Attempted: `build/sbt 'sql/testOnly org.apache.spark.sql.jdbc.JDBCV2Suite -- -z "DataFrameWriterV2: truncate closes JDBC connections"'` The local build was blocked while compiling unrelated Parquet test sources because `org.apache.parquet.column.values.Utils` and `org.apache.parquet.column.page.mem.MemPageStore` were unavailable. The new test's missing `JDBCOptions` import was fixed before that unrelated failure. ### Was this patch authored or co-authored using generative AI tooling?
