[jira] Updated: (HADOOP-676) JobClient should print user friendly
messages for standard errors
[ http://issues.apache.org/jira/browse/HADOOP-676?page=all ]
Sanjay Dahiya updated HADOOP-676:
---------------------------------
Attachment: Hadoop-676.patch
This patch adds 3 new exceptions
- InvalidJobConfException (mendatory attributes missing or incorrect)
- InvalidFileTypeException (expecting file / got dir or vice versa )
- FileAlreadyExistsException (as it says)
It throws these exceptions from job client and prints better error messages. All exceptions extend IOException to conform with existing API but are added in throws declaration to appear in javadocs.
Is there any other exception you would like to be thrown/printed ?
