Yuanjian Li 6484c14c57 [SPARK-32115][SQL] Fix SUBSTRING to handle integer overflows ... ### What changes were proposed in this pull request? Bug fix for overflow case in `UTF8String.substringSQL`. ### Why are the changes needed? SQL query `SELECT SUBSTRING("abc", -1207959552, -1207959552)` incorrectly returns` "abc"` against expected output of `""`. For query `SUBSTRING("abc", -100, -100)`, we'll get the right output of `""`. ### Does this PR introduce _any_ user-facing change? Yes, bug fix for the overflow case. ### How was this patch tested? New UT. Closes #28937 from xuanyuanking/SPARK-32115. Authored-by: Yuanjian Li <xyliyuanjian@gmail.com> Signed-off-by: Dongjoon Hyun <dongjoon@apache.org>		2020-06-28 12:22:44 -07:00
