Hi All:
I am setting up 2 grids, each with its own HDFS. The grids are unaware of each
other but exist on the same network.
I'd like to copy data from one HDFS to the other. Is there a way to do this
simply, or do I need to cobble together scripts to copy from HDFS on one side
and pipe to a dfs -cp on the other side?
I tried something like this:
hadoop dfs -ls hdfs://grid1NameNode:portNo/
from grid2 trying to ls on grid1 but got a "wrong FS" error message. I also
tried:
hadoop dfs -ls hdfs://grid1NameNode:portNo/foo
on grid2 where "/foo" exists on grid1 and got 0 files found.
I assume there is some way to do this and I just don't have the right command
line magic. This is Hadoop 0.15.0.
Any help appreciated.
Thanks,
C G
