Subject Re: unable to empty the connection queue between 2 processors in NIFI secure cluster
Date Mon, 14 Nov 2016 05:44:35 GMT
Thanks Andrew, I finally got it to work. it turns out I had to add
permissions for all the node identities in the global "query provenance"
policy setting menu as well as inside the operator menu for that processor
group. these node identities are configured inside the cluster
configuration file authorizers.xml as below:
        <property name="Node Identity 1">CN=CentOS1, OU=NIFI</property>
        <property name="Node Identity 2">CN=CentOS2, OU=NIFI</property>
        <property name="Node Identity 3">CN=CentOS3, OU=NIFI</property>
