Subject [GitHub] [flink] SteNicholas opened a new pull request #14028: [FLINK-20020][client] Make UnsuccessfulExecutionException part of the JobClient.getJobExecutionResult() contract
Date Wed, 11 Nov 2020 05:58:59 GMT

SteNicholas opened a new pull request #14028:
URL: https://github.com/apache/flink/pull/14028

   ## What is the purpose of the change
   *Currently, different implementations of the `JobClient` throw different exceptions. The
`ClusterClientJobClientAdapter` wraps the exception from the `JobResult.toJobExecutionResult()`
into a `ProgramInvocationException`, the `MiniClusterJobClient` simply wraps it in a `CompletionException`
and the `EmbeddedJobClient` wraps it into an `UnsuccessfulExecutionException`. `JobResult.toJobExecutionResult()`
should make the exception uniform and part of the contract through `JobExecutionResultException`
which exception includes the status of the application.*
   ## Brief change log
     - *Add `JobExecutionResultException` to make the exception uniform and part of the contract
for `JobResult.toJobExecutionResult()`.*
     - *`ClusterClientJobClientAdapter`, `MiniClusterJobClient` and `EmbeddedJobClient` uniform
the exception to `JobExecutionResultException`.*
   ## Verifying this change
     - *Modify `ApplicationDispatcherBootstrapTest` and `PerJobMiniClusterFactoryTest.java`
to update the `UnsuccessfulExecutionException` check to the `JobExecutionResultException`.*
