To: [email protected] Date: Monday, September 7, 2009, 1:45 AM Hi All: Does anybody know if it's possible to distcp between an old version of Hadoop (0.15.x, for example) and a modern version (0.19.2)? A quick check trying to move from an "old" grid to a "new" grid shows a "Incorrect header or version mismatch" error in the new grid's NameNode log, and a SocketTimeOut exception on the distcp on the old grid. Any help/info most appreciated. Thanks,C G
