Error shown before deploying hdf cluster with an existing hdp cluster

[#1]

I was installing HDF cluster with an existing HDP cluster, the deploy option turned red and an error message arrived it says

"If NiFi Certificate Authority is used, nifi.toolkit.tls.token must be set"

"This is a token that will be used by the NiFi Certificate Authority to verify the identity of NiFi nodes before issuing them certificates and by the NiFi nodes to verify the identity of the NiFi Certificate Authority. If relying on NiFi Certificate Authority, set this to a long, random value. For security purposes, password changes will not be shown in configuration version comparisons"

Help me fix this issue

The alert is just indicating you need to enter a value where one is missing.   Scroll down inside of the page (not the whole page), and you should be able to find the missing value.   Another fast way to get where you want is to search/filter for nifi.toolkit.tls.token which will take you directly to it.

Once the alert/error is satisfied the NEXT button on the bottom of the page will work again.
