Subject How to concatenate hadoop files to a single hadoop file
Date Thu, 02 Oct 2008 19:17:20 GMT
Suppose I have 3 files in Hadoop that I want to "cat" them to a single file. I know it can
be done by "hadoop dfs -cat" to a local file and updating it to Hadoop. But it's very expensive
for large files. Is there an internal way to do this in Hadoop itself? Thanks
