Subject discyp between different versions of Hadoop...
Date Mon, 07 Sep 2009 05:45:28 GMT
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
