Failed to Start Nifi on HDF3.0

[#1]

Hi,

When I click the Nifi start button on Ambari, it would become green for a second, but immediately become red. I got the below error in nifi-app.log. It complains 'Address already in use', but I confirmed no process on the node was using 9090 port. Does anyone happen to experience this and know the resolution?

[#2 · Accepted solution]

@yjiang Have you installed NiFi on the same server as Superset? They have a default port clash on 9088 - I suggest you search in the NiFi configs for 9088 and change it to 9089 (9089 is free in a default install).

Thanks @Dan Chaffelson

Changing Nifi protocol port to 9089 works.

[#4]

Got the same error. Your hint works.
