You can locate the hadoop-core jar (assuming it is compatible with 1.0.3), make a copy of it and either move it aside or rename it to an extension other than .jar. Then you can copy hadoop-1.0.3-core-SNAPSHOT.jar to the same location.
The above should be done for all nodes. Cheers On Mon, Feb 2, 2015 at 6:54 AM, Bo Fu <b...@uchicago.edu> wrote: > Hi all, > > I have a stupid question.
