Wenchen Fan 6b34e745bb [SPARK-19178][SQL] convert string of large numbers to int should return null ... ## What changes were proposed in this pull request? When we convert a string to integral, we will convert that string to `decimal(20, 0)` first, so that we can turn a string with decimal format to truncated integral, e.g. `CAST('1.2' AS int)` will return `1`. However, this brings problems when we convert a string with large numbers to integral, e.g. `CAST('1234567890123' AS int)` will return `1912276171`, while Hive returns null as we expected. This is a long standing bug(seems it was there the first day Spark SQL was created), this PR fixes this bug by adding the native support to convert `UTF8String` to integral. ## How was this patch tested? new regression tests Author: Wenchen Fan <wenchen@databricks.com> Closes #16550 from cloud-fan/string-to-int.		2017-01-12 22:52:34 -08:00
