nifi the specified observer identifier already exists

Explorer

HI,

We have a test hdf cluster of 3 nodes, and another product hdf cluster of 3 nodes. I export 8 dataflow template from test cluster, and I import the template to product cluster. But the error "the specified observer identifier already exists" happen. I would like to know what is the reason, and how to avoid the issue. so I can use template perfectly.

Thanks

Paul

Could you provide the version of NiFi you are using?

You may be bumping into this issue, which was fixed in 1.0.1: https://issues.apache.org/jira/browse/NIFI-3129

The issue occurred with earlier versions when a template had the same Controller Service used twice in in the process group.
