Install option failure-threshold not working

Hi,

I'm trying to install Vertica 8.0 on linux server (RHEL6), I've got one warning and one hint error and I want to omit this errors with this option --failure-threshold WARN but it doesn't work ...

My install command:

/opt/vertica/sbin/install_vertica --hosts auric --rpm /home/vertica/RPM/vertica-8.0.1-0.x86_64.RHEL6.rpm --dba-user vertica --dba-group dba --data-dir /usr3/vertica/data/ --failure-threshold WARN

My log:

Hint: Fix above failures or use --failure-threshold
