[jira] [Commented] (STORM-545) DRCP does not return a cause of
failure
[ https://issues.apache.org/jira/browse/STORM-545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14316682#comment-14316682 ]
Robert Joseph Evans commented on STORM-545:
-------------------------------------------
The hardest part here is we need an additional thrift API so that the error message can be sent back.

> Throwing the {{backtype.storm.topology.FailedException}} is a way to report an error. Unfortunately the clue of the error is not transmitted to the {{backtype.storm.utils.DRPCClient}}. {{DRPCClient}} catches {{backtype.storm.generated.DRPCExecutionException}} that does not carry any cause. It carries a static message ??"Request failed"??.
> The optimal solution would be carrying {{FailedException}} or its subclass, or at least its message.
