…Task
Today DataSource Task pull InputSplits from JobManager to achieve better
performance, however, when a DataSourceTask failed and rerun, it will
not get the same splits as its previous version. this will introduce
inconsistent result or even data corruption.
Furthermore, if there are two executions run at the same time (in batch
scenario), this two executions should process same splits.
we need to fix the issue to make the inputs of a DataSourceTask
deterministic. The propose is save all splits into ExecutionVertex and
DataSourceTask will pull split from there.

*Thank you very much for contributing to Apache Flink - we are happy that you
want to help us improve Flink. To help the community review your contribution
in the best possible way, please go through the checklist below, which will get
the contribution into a shape in which it can be best reviewed.*
*Please understand that we do not do this to make contributions to Flink a
hassle. In order to uphold a high standard of quality for code contributions,
while at the same time managing a large number of contributions, we need
contributors to prepare the contributions well, and give reviewers enough
contextual information for the review. Please also understand that
contributions that do not follow this guide will take longer to review and thus
typically be picked up with lower priority by the community.*
## Contribution Checklist
- Make sure that the pull request corresponds to a [JIRA
issue](https://issues.apache.org/jira/projects/FLINK/issues). Exceptions are
made for typos in JavaDoc or documentation files, which need no JIRA issue.
- Name the pull request in the form "[FLINK-XXXX] [component] Title of the
pull request", where *FLINK-XXXX* should be replaced by the actual issue
number. Skip *component* if you are unsure about which is the best component.
Typo fixes that have no associated JIRA issue should be named following this
pattern: `[hotfix] [docs] Fix typo in event time introduction` or `[hotfix]
[javadocs] Expand JavaDoc for PuncuatedWatermarkGenerator`.
- Fill out the template below to describe the changes contributed by the pull
request. That will give reviewers the context they need to do the review.
- Make sure that the change passes the automated tests, i.e., `mvn clean
verify` passes. You can set up Travis CI to do that following [this
guide](http://flink.apache.org/contribute-code.html#best-practices).
- Each pull request should address only one issue, not mix up code from
multiple issues.
- Each commit in the pull request has a meaningful commit message (including
the JIRA id)
- Once all items of the checklist are addressed, remove the above text and
this checklist, leaving only the filled out template below.
**(The sections below can be removed for hotfixes of typos)**
## What is the purpose of the change
*(For example: This pull request makes task deployment go through the blob
server, rather than through RPC. That way we avoid re-transferring them on each
deployment (during recovery).)*
## Brief change log
*(for example:)*
- *The TaskInfo is stored in the blob store on job creation time as a
persistent artifact*
- *Deployments RPC transmits only the blob storage reference*
- *TaskManagers retrieve the TaskInfo from the blob cache*
## Verifying this change
*(Please pick either of the following options)*
This change is a trivial rework / code cleanup without any test coverage.
*(or)*
This change is already covered by existing tests, such as *(please describe
tests)*.
*(or)*
This change added tests and can be verified as follows:
*(example:)*
- *Added integration tests for end-to-end deployment with large payloads
(100MB)*
- *Extended integration test for recovery after master (JobManager) failure*
- *Added test that validates that TaskInfo is transferred only once across
recoveries*
- *Manually verified the change by running a 4 node cluser with 2 JobManagers
and 4 TaskManagers, a stateful streaming program, and killing one JobManager
and two TaskManagers during the execution, verifying that recovery happens
correctly.*
