[jira] Created: (MAPREDUCE-1597) combinefileinputformat does not
work with non-splittable files
combinefileinputformat does not work with non-splittable files
--------------------------------------------------------------
Key: MAPREDUCE-1597
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1597
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Namit Jain
CombineFileInputFormat.getSplits() does not take into account whether a file is splittable.
This can lead to a problem for compressed text files - for example, getSplits() may return more
than 1 split depending on the size of the compressed file, all the splits recordreader will read the
complete file.
I ran into this problem while using Hive on hadoop 20.
