[SPARK-26379][SS][BRANCH-2.3] Use dummy TimeZoneId to avoid UnresolvedException in CurrentBatchTimestamp by HeartSaVioR · Pull Request #23656 · apache/spark

HeartSaVioR · 2019-01-25T23:40:52Z

What changes were proposed in this pull request?

Spark replaces CurrentTimestamp with CurrentBatchTimestamp.
However, CurrentBatchTimestamp is TimeZoneAwareExpression while CurrentTimestamp isn't.
Without TimeZoneId, CurrentBatchTimestamp becomes unresolved and raises UnresolvedException.

Since CurrentDate is TimeZoneAwareExpression, there is no problem with CurrentDate.

How was this patch tested?

Pass the Jenkins with the updated test cases.

…to streaming query ## What changes were proposed in this pull request? This patch proposes to fix issue on adding `current_timestamp` / `current_date` with streaming query. The root reason is that Spark transforms `CurrentTimestamp`/`CurrentDate` to `CurrentBatchTimestamp` in MicroBatchExecution which makes transformed attributes not-yet-resolved. They will be resolved by IncrementalExecution. (In ContinuousExecution, Spark doesn't allow using `current_timestamp` and `current_date` so it has been OK.) It's OK for DataSource V1 sink because it simply leverages transformed logical plan and don't evaluate until they're resolved, but for DataSource V2 sink, Spark tries to extract the schema of transformed logical plan in prior to IncrementalExecution, and unresolved attributes will raise errors. This patch fixes the issue via having separate pre-resolved logical plan to pass the schema to StreamingWriteSupport safely. ## How was this patch tested? Added UT.

We will revisit this PR because the original PR needs a more verification and a followup PR is expected.

Hi, @HeartSaVioR . Could you update this PR with the final content?

…xception in CurrentBatchTimestamp ## What changes were proposed in this pull request? Spark replaces `CurrentTimestamp` with `CurrentBatchTimestamp`. However, `CurrentBatchTimestamp` is `TimeZoneAwareExpression` while `CurrentTimestamp` isn't. Without TimeZoneId, `CurrentBatchTimestamp` becomes unresolved and raises `UnresolvedException`. Since `CurrentDate` is `TimeZoneAwareExpression`, there is no problem with `CurrentDate`.

HeartSaVioR · 2019-01-28T14:48:02Z

Yeah... If the branch should be maintained further, it may need to fix the flaky tests... As it seems to be known flakiness, are we aware about the fix in upper version lines?

2 failures, 1 passes. It looks like kind of serious one if Spark community will maintain branch-2.3 forward.

dongjoon-hyun · 2019-01-28T20:12:59Z

@HeartSaVioR . Yes. It's true and branch-2.3 will be EOF in several months.

dongjoon-hyun · 2019-01-28T20:13:08Z

Merged to branch-2.3.

maropu · 2019-01-29T00:59:23Z

@HeartSaVioR I'm not familiar with the SS part though, your other pr (#23634) is not related to the failures? It seems the failures are of the outer joins tests...

HeartSaVioR · 2019-01-29T01:03:00Z

If #23634 was the fix for tests they would be flaky for branch-2.4 / master as well. They don't seem to be flaky in master branch.
