Hi,
I am trying to copy data between HDFS that are located away from each
other, and when I run the distcp command, I get the errors below in the
namenode and the datanode of the target hosts. What is happening?
The 2 mapreduce runtime are running in a VLAN. The host are physically
distant, but they use the same IP range.
Command:
hadoop distcp hdfs://WorkGroup0000:9000/wiki hdfs://WorkGroup0010:9000/wiki
