[shriharish1310]

Issue

• My PR fully resolves the following issue, referenced in the PR title:
  • Resolves Improve testing of row and sort key fields in BulkImportJobDriverIT #7199

What changed

• Added integration coverage for LongType, StringType, and ByteArrayType in both row-key and sort-key positions.
• Runs every key-type case through the DataFrame, RDD, and DataFrame local-sort bulk-import drivers.
• Verifies the imported Parquet rows preserve their values and are returned in schema-defined key order.

Tests

• My PR adds tests based on the project test strategy:
  • BulkImportJobDriverIT: 30 tests passed, including 9 new key-type/runner combinations; 0 failures, 0 errors, 0 skipped.
  • mvn --batch-mode -pl bulk-import/bulk-import-runner verify -DrunIT=BulkImportJobDriverIT -DskipRust (Linux container)
  • mvn --batch-mode -pl bulk-import/bulk-import-runner -Pstyle -DskipRust checkstyle:check spotbugs:check

Documentation

• No documentation change is needed because this is test-only coverage with no user-facing functionality change.
• No production Java code was added, so no new Javadoc is required.
• No dependencies were added or removed, so NOTICES is unchanged.

Hi maintainers - the CLA Assistant page for this PR loads with an empty Version and no agreement text, so I am unable to review or sign it. I have also updated the commit author identity to match the PR account. Could you please check or refresh the repository's CLA Assistant configuration? Thanks!

It looks like that was a temporary problem with the CLA Assistant. The agreement seems to be loading again now, although it takes a few seconds to show. Sorry about that.
