Caused by: java.io.IOException: java.io.IOException: error=2, No such file or directory

Cause:
Utilities such as ifconfig / netstat have been marked as deprecated for CentOS 7, and the 'net-tools' package is no longer part of the @core group so will not be installed by default.

Resolution:
To resolve the issue, enter the following command in terminal to install the net-tools package on the affected client computer:

>yum install net-tools
