Error installing Install CDH 6.3.3

Hi,

Following the instruction described on this page:

https://docs.cloudera.com/documentation/enterprise/6/latest/topics/installation.html

I made some good progress until up to step 6:  Install CDH and Other Software:

Now I encountered error. Please see the picture below:

I completely wiped out the databases, retried twice, and still seeing the error. Could you advise where to check to fix the trouble, and move forward? Thank you!
