error reporting: PigException needs to have a way to indicate that its message
is appropriate for user
------------------------------------------------------------------------------------------------------
Key: PIG-1612
URL: https://issues.apache.org/jira/browse/PIG-1612
Project: Pig
Issue Type: Improvement
Reporter: Thejas M Nair
Fix For: 0.9.0
The error message printed to the user by pig is the message from the exception
that is the 'root cause' from the chain of getCause() of exception that has
been thrown. But often the 'root cause' exception does not have enough context
that would make for a better error message. It should be possible for a
PigException to indicate to the code that determines the error message that its
getMessage() string should be used instead of that of the 'cause' exception.
The following code in LogUtils.java is used to determine the exception that is
the 'root cause' -
{code}
public static PigException getPigException(Throwable top) {
Throwable current = top;
Throwable pigException = top;
while (current != null && current.getCause() != null){
current = current.getCause();
if((current instanceof PigException) &&
(((PigException)current).getErrorCode() != 0)) {
pigException = current;
}
}
return (pigException instanceof PigException?
(PigException)pigException : null);
}
{code}
