Hi,
I have a question to the hadoop experts:
I have two HDFS, in different subnet.
HDFS1 : 192.168.*.*
HDFS2: 10.10.*.*
the namenode of HDFS2 has two NIC. One connected to 192.168.*.* and another
to 10.10.*.*.
So, is it possible to transfer data from HDFS1 to HDFS2 and vice versa.
Regards,
A
If you could cross-access HDFS from both name nodes, then it should be
transferable using /distcp /command.

I can not cross access HDFS. Though HDFS2 has two NIC the HDFS is running
on the other subnet.

It seems in your case HDFS2 could access HDFS, so you should be able to
transfer HDFS data to HDFS2.
If you want to cross-transfer, you don't need to do distcp on cluster
nodes, if any client node (not necessary to be namenode, datanode,
secondary node, etc.) could access to both HDFSs, then r
Looks like both are private subnets, so you got to route via a public
default gateway. Try adding route using route command if your in
linux(windows i have no idea). Just a thought i havent tried it though.

So,
hadoop dfs -cp hdfs:// hdfs://...
this will work.
