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'.

2. Every time I launch a command in YARN I get a java hotspot warning
(warning below). How I remove the Java HotSpotWarning?
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'.
Thanks,
