Hi,
1 - I have HDFS running with WebHDFS protocol. I want to copy data from
local disk to HDFS, but I get the error below. How I copy data from the
local disk to HDFS?
|xubuntu@hadoop-coc-1:~/Programs/hadoop$ hdfs dfs -copyFromLocal ~/input1
webhdfs://192.168.56.101:8080/
Java HotSpot(TM) Client VM warning: You have loaded library
/home/xubuntu/Programs/hadoop-2.6.0/lib/native/libhadoop.so which might have
disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>',
or link it with '-z noexecstack'.
