Re: Processor using Kerberos keytab auth - can't renew TGT

Hi Joe, we recently had a similar problem. For us it turned out that we are using the latest open-jdk8 which no longer is providing the JCE policies required for strong cryptography out of the box on cents 7.3. regards, Georg Joe Witt schrieb am Fr., 14. Juli 2017 um 15:12

Re: NiFi web interface not starting

I think we found a solution. I am not exactly sure what has helped but renewing kerberos tokens seems to have done the trick. Georg Heiler <georg.kf.hei...@gmail.com> schrieb am Di. 13. Juni 2017 um 10:44: > Please see the logs below from the commands you suggested > > [root@devbox

Kerberos hive failure to renew tickets

Hi In production I observe problems with ticket renewal for the nifi hive processor. A workaround is to restart the hive service but that doesn't seem right. Is there a real fix for this problem? Best Georg

Registry, sdlc and promotion between environments

Hi Can I use the new nifi registry to promote / move my nifi flows between environments? To me it currently looks like I can only click around in a single environment and then follow up / diff the changes over time via the registry. Also can the registry integrate with git? Best Georg

Logical view of flow for error handling

Dynamic XPath

Hi, how can I support dynamic XPath queries in NiFi? http://apache-nifi.1125220.n5.nabble.com/Expression-language-support-in-EvaluateXPath-td18041.html states that due to performance wifi expression language is not supported for dynamic x-path queries. Has there been any progress regarding this?
