Hello everyone, Does anybody know where I can configure a new flow persistence provider for Nifi Registry using Cloudera Manager? I tried the escape valve for staging/providers.xml, but I get a validation error if I enter the required value to integrate NiFi Registry with Git: <flowPersistenceProvider>
<class>org.apache.nifi.registry.provider.flow.git.GitFlowPersistenceProvider</class>
<property name="Flow Storage Directory">{{nifi_registry_internal_dir}}/git/perso-recognition-nifi-flows</property>
<property name="Remote To Push">origin</property>
<property name="Remote Access User">paulvid</property>
<property name="Remote Access Password">[your_key]</property>
</flowPersistenceProvider> I'm following this guide to configure Nifi Registry with Git: https://community.hortonworks.com/articles/222365/how-to-configure-git-for-nifi-registry-in-hdf-32.h... , but the xml configuration differs from Ambari to Cloudera Manager. I was able to make CM generate the correct providers.xml by using the properties below: Which results on the following providers.xml: [root@nifi1 399-nifiregistry-NIFI_REGISTRY_SERVER]# cat providers.xml
<providers>
<flowPersistenceProvider>
<class>org.apache.nifi.registry.provider.flow.FileSystemFlowPersistenceProvider</class>
<property name="Flow Storage Directory">/var/lib/nifiregistry/flow_storage</property>
</flowPersistenceProvider>
<flowPersistenceProvider>
<class>org.apache.nifi.registry.provider.flow.git.GitFlowPersistenceProvider</class>
<property name="Remote Access User">yyy</property>
<property name="Flow Storage Directory">/var/lib/nifi-registry/git/nifi_registry_demo</property>
<property name="Remote Access Password">xxx</property>
<property name="Remote to Push">origin</property>
</flowPersistenceProvider> But now I'm getting this error starting the Nifi service: ...
