Hi all, I nifi I have an attribute with filename from which I extracted date with substring (only yyyyMMdd portion). After that I want to calculate year week number for date 2018/08/19 (formated from string portion 20180819024112) which is week number 33. If I use format without specified timezone ('GMT'), I get week number 34, but with specified timezone I get correct week number 33. What is the difference? Why do I get wrong week number without timezone. GMT is only +2 hours from 19th of August Midnight. Thanks, Tom ... View more

Hi to all, I configured Nifi on HDP cluster to authenticate users using kerberos. HDP 2.6.0.3 Ambari 2.5.0.3 Nifi 1.2.0 I changed nifi.properties, authorizers.xml and login-identity-providers.xml ccording to docs and when I restarted Nifi a get this in nifi-app.log Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'x509AuthenticationProvider' defined in class path resource [nifi-web-security-context.xml]: Cannot resolve reference to bean 'authorizer' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'authorizer': FactoryBean threw exception on object creation; nested exception is java.lang.Exception: Unable to load the authorizer configuration file at: /usr/hdf/current/nifi/conf/authorizers.xml Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'userGroupProvider'. One of '{authorizer}' is expected. Authorizer is managed-authorizer and I put xml conf in following order <userGroupProvider> <accessPolicyProvider> <authorizer> I even try to formatt XML config entries in case it can't parse XML, but exception is still there after restart. Any ideas? Thank you. ... View more
