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). -- This message is automatically generated by JIRA.
