Subject [jira] Created: (HADOOP-1441) Splittability of input should be controllable by application
Date Tue, 29 May 2007 23:08:17 GMT
Splittability of input should be controllable by application
------------------------------------------------------------

                 Key: HADOOP-1441
                 URL: https://issues.apache.org/jira/browse/HADOOP-1441
             Project: Hadoop
          Issue Type: Improvement
          Components: mapred
    Affects Versions: 0.12.3
         Environment: ALL
            Reporter: Milind Bhandarkar
             Fix For: 0.14.0


Currently, isSplittable method of FileInputFormat always returns true. For some applications,
it becomes necessary that the map task process entire file, rather than a block. Therefore,
splittability of input (i.e. block-level split vs file-level-split) should be controllable
by user via a configuration variable. The default could be block-level split, as is.
