### What changes were proposed in this pull request? This is a followup PR for SPARK-33690 (#30647) . In addition to the original PR, this PR intends to escape the following meta-characters in `Dataset#showString`. * `\r` (carrige ret) * `\f` (form feed) * `\b` (backspace) * `\u000B` (vertical tab) * `\u0007` (bell) ### Why are the changes needed? To avoid breaking the layout of `Dataset#showString`. `\u0007` does not break the layout of `Dataset#showString` but it's noisy (beeps for each row) so it should be also escaped. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Modified the existing tests. I also build the documents and check the generated html for `sql-migration-guide.md`. Closes #31144 from sarutak/escape-metacharacters-in-getRows. Authored-by: Kousuke Saruta <sarutak@oss.nttdata.com> Signed-off-by: Sean Owen <srowen@gmail.com> |
