Subject [jira] Created: (HADOOP-1442) Zero-byte input files are not included in InputSplit
Date Tue, 29 May 2007 23:44:15 GMT
Zero-byte input files are not included in InputSplit
----------------------------------------------------

                 Key: HADOOP-1442
                 URL: https://issues.apache.org/jira/browse/HADOOP-1442
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.12.3
         Environment: ALL
            Reporter: Milind Bhandarkar
             Fix For: 0.14.0


The default FileInputFormat::getSplits method does not include zero-byte input files in FileSplit[].
Applications that assume the minimum number of maps to be at least number of input files can
get bitten by this, as well as  applications that use -reducer NONE to produce number of partitions
that are equal to input partitions.
