org apache hadoop yarn exceptions YarnRuntimeException Permissions incorrectly set for dir problem

Question

can someone explain me what's the reason for this? and how to fix it. I've looking the net but could'nt understand how to fix it. 

Answer 1

This error is caused when hadoop tries to use a direct but it is not able to because the directory does not have suitable permissions. If you observe the error, you can see that the error states that the permissions are not right for the directory "/tmp/hadoop-ASUS/nm-local-dir/nmPrivate". The error has also mentioned the right permissions to be set to solve this error. Change the permissions of directory and the error will be solved.

how to change the permissions of directory?

You can change the permission of the directory using the chmod command. Syntax is as follows:

chmod <permissions> <path to directory>

In your case, it would be 

chmod 700 /tmp/hadoop-ASUS/nm-local-dir/nmPrivate
