----------------------------------------
Summary: Deadlock when updating flow configuration from predefined
nifi.c2.flow.url
Key: MINIFICPP-2087
URL: https://issues.apache.org/jira/browse/MINIFICPP-2087
Project: Apache NiFi MiNiFi C++
Issue Type: Bug
Reporter: Gábor Gyimesi
Assignee: Gábor Gyimesi
When flow configuration is not available on disk under the configuration
library and C2 is enabled with a predifined "nifi.c2.flow.url" property, the
initial workflow fetching causes a deadlock.
