Revision fdea642dbd17d74c8bf136c1746159acaa937d25 authored by donnyzone on 18 August 2017, 05:37:32 UTC, committed by gatorsmile on 18 August 2017, 05:37:41 UTC
## What changes were proposed in this pull request? https://issues.apache.org/jira/projects/SPARK/issues/SPARK-21739 This issue is caused by introducing TimeZoneAwareExpression. When the **Cast** expression converts something into TimestampType, it should be resolved with setting `timezoneId`. In general, it is resolved in LogicalPlan phase. However, there are still some places that use Cast expression statically to convert datatypes without setting `timezoneId`. In such cases, `NoSuchElementException: None.get` will be thrown for TimestampType. This PR is proposed to fix the issue. We have checked the whole project and found two such usages(i.e., in`TableReader` and `HiveTableScanExec`). ## How was this patch tested? unit test Author: donnyzone <wellfengzhu@gmail.com> Closes #18960 from DonnyZone/spark-21739.
