Description

If my complete hostname is host1.abc.xyz.com, only complete hostname must be used to access data via hdfs://

I am running following in .20.205 Client to get data from .20.205 NN (host1)
$hadoop dfs -copyFromLocal /etc/passwd hdfs://host1/tmp
copyFromLocal: Wrong FS: hdfs://host1/tmp, expected: hdfs://host1.abc.xyz.com
Usage: java FsShell [-copyFromLocal <localsrc> ... <dst>]

$hadoop dfs -copyFromLocal /etc/passwd hdfs://host1.abc/tmp/
copyFromLocal: Wrong FS: hdfs://host1.blue/tmp/1, expected: hdfs://host1.abc.xyz.com
Usage: java FsShell [-copyFromLocal <localsrc> ... <dst>]

$hadoop dfs -copyFromLocal /etc/passwd hftp://host1.abc.xyz/tmp/
copyFromLocal: Wrong FS: hdfs://host1.blue/tmp/1, expected: hdfs://host1.abc.xyz.com
Usage: java FsShell [-copyFromLocal <localsrc> ... <dst>]

Only following is supported
$hadoop dfs -copyFromLocal /etc/passwd hdfs://host1.abc.xyz.com/tmp/
