Subject [jira] Commented: (MAPREDUCE-1921) IOExceptions should contain the filename of the broken input files
Date Thu, 10 Feb 2011 00:16:58 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1921?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12992807#comment-12992807
] 

Tom White commented on MAPREDUCE-1921:
--------------------------------------

We could make this slightly more general by not restricting to FileSplit. By using InputSplit's
toString() method we get more information for FileSplit (path plus offset and length), and
it works for other InputSplit implementations too.

> If bzip or other decompression fails, the IOException  does not contain the name of the
broken file that caused the exception.
> It would be nice if such actions could be avoided in the future by having the name of
the files that are broken spelled
> out in the exception.
