Subject Re: Hadoop 2.6.0: "FileSystem file:/// is not a distributed file system"
Date Tue, 16 Dec 2014 15:31:04 GMT
Thanks, the error now changes to the following:
$ hadoop dfsadmin -report
report: Server IPC version 9 cannot communicate with client version 4

Not clear which Server and which client are conflicting. All hadoop
components comes from the hadoop-2.6.0.tar.gz package, what's going wrong?

Cheers,
Dan
