Subject [jira] Commented: (HADOOP-5201) getDiagnostics in TaskReport should return exceptions
Date Wed, 18 Mar 2009 17:33:50 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12683104#action_12683104

Santhosh Srinivasan commented on HADOOP-5201:

Yes, that is exactly what I do. Most of them get thrown. You can look at the source at the
following location. In particular look at the method getExceptionFromString

> Currently, getDiagnostics() returns Strings. When exceptions are thrown in user code
and/or Hadoop, it would be cleaner to propagate the exception back to the application for
better error handling. Hadoop should return the exceptions instead of returning string representations
that correspond to printStackTrace() output.
