Installing NiFi on a New HDP Cluster
If you are installing NiFi on a new HDP installation, as opposed to an upgraded HDP installation, follow the instructions at Installing NiFi on a New HDP Cluster.
In addition to other settings for the Advanced nifi-ambari-ssl-config, you must add a node identify for the Knox node.
For example:
<property name="Node Identity1">CN=$NIFI_HOSTNAME, OU=NIFI</property>
<property name="Node Identity2">CN=$NIFI_HOSTNAME, OU=NIFI</property>
<property name="Node Identity3">CN=$NIFI_HOSTNAME, OU=NIFI</property>
<property name="Node Identity4">CN=$KNOX_HOSTNAME, OU=KNOX</property>
