Hi - upgraded from HDF 2.x -> 3.0 (ran into issue with upgrade so wiped everything 2.x related and installed 3). Getting the below error in app log during startup. Everything done through Ambari

2017-06-29 20:11:31,391 ERROR [NiFi logging handler] org.apache.nifi .StdErr Failed to start web server: Error creating bean with name 'niFiWebApiSecurityConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.apache.nifi .web.NiFiWebApiSecurityConfiguration.setJwtAuthenticationProvider(org.apache.nifi.web.security.jwt.JwtAuthenticationProvider); nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jwtAuthenticationProvider' defined in class path resource [nifi-web-security-context.xml]: Cannot resolve reference to bean 'jwtService' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jwtService' defined in class path resource [nifi-web-security-context.xml]: Cannot resolve reference to bean 'keyService' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'keyService' defined in class path resource [nifi-administration-context.xml]: Cannot resolve reference to bean 'keyTransactionBuilder' while setting bean property 'transactionBuilder'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'keyTransactionBuilder' defined in class path resource [nifi-administration-context.xml]: Cannot resolve reference to bean 'keyDataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'keyDataSource': FactoryBean threw exception on object creation; nested exception is org.h2.jdbc.JdbcSQLException: Error while creating file "/data/1/nifi/database_repository_rock" [90062-176]

I do see:

2017-06-29 20:11:10,586 - Creating directory Directory['/data/1/nifi/database_repository'] since it doesn't exist. 2017-06-29 20:11:10,586 - Changing owner for /data/1/nifi/database_repository_rock from 0 to nifi

2017-06-29 20:11:10,586 - Changing group for /data/1/nifi/database_repository_rock from 0 to nifi

Permissions and everything looks to be set correctly. Have tried completely removing /data/1/* and clearing other remnants of previous install. any ideas or places I should look? Only happens

@ mliem Did you copy the flow.xml.gz from your old installation to this one after you wiped everything 2.x related and installed 3. All the sensitive properties inside the flow.xml.gz file are encrypted using the sensitive property defined in the nifi.properties file (If blank, NiFi uses an internal default value). If you move your flow.xml.gz file to another NiFi, the sensitive property value used must be the same or NiFi will fail to start because it cannot decrypt the sensitive properties in the file.
