Subject [jira] Commented: (HADOOP-3844) include message of local exception in Client call failures
Date Fri, 14 Nov 2008 14:40:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3844?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12647617#action_12647617

Steve Loughran commented on HADOOP-3844:
----------------------------------------

actually, this patch isnt the root cause, as the exception was already being wrapped. So this
bit of code may have been brittle for some time.

> When Client fails with a local exception, that exception is retained, but the message
is not propagated to the new exception text, which becomes simply  "Call failed on local exception"
> The forthcoming patch will change such messages to include that of the nested exception,
so producing test reports containing useful data such as
> java.io.IOException: Call failed on local exception: Connection refused
