Date Tue, 08 Jan 2013 11:04:12 GMT
Ranadip created HADOOP-9187:
-------------------------------

             Summary: FileUtil.CopyMerge should handle compressed input and output
                 Key: HADOOP-9187
                 URL: https://issues.apache.org/jira/browse/HADOOP-9187
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs
            Reporter: Ranadip


This method, if run on compressed input, results in corrupt output since it just does a byte-by-byte
concatenation disregarding compression codecs. It should automatically detect compression
codecs from input files and handle them intelligently. 
Additionally, there should be an option to create a compressed output file so that the output
can be efficiently stored and sent out to customers (over the network outside the cluster).
