Hey Guys ( @Matt Clarke ) , Does anyone know why the SelectHiveQL processor does *not* copy the flowfile attributes of the incoming flowfile to the outgoing flowfile (unlike other processors)? I've had to do some crafty things to workaround this. For example, modify my SQL to embed the flowfile attributes I would like to propogate... ie: select interesting_stuff, 'attribute_1_val' as attribute_1_key from table. I was thinking of creating a custom processor by subclassing SelectHiveQL processor to fix this issue but I wanted to ask: 1) Does anyone know if this is a known issue with a known fix? ...

Hey Guys, Is it possible to access the Processor Group variables within the ExecuteScript Processor? I would specifically be interested in the syntax for doing that with Ruby. Any guidance would be appreciated. ... View more

Hey Guys, In addition to sending back the status code (which I do with HandleHttpResponse => Http Response Code"), I would like to set a custom status message. For example: Status: 400 Status Message: "You are not authorized" Any pointers would be appreciated. ... View more

Hey Guys, We are running Nifi on a cluster of two nodes. In the last 5 weeks, the flow.xml.gz file has gotten out of sync twice. What are some situations that will defeat Nifi's replication of this file? Is there anything we can do to mitigate the likelihood of this happening again? ... View more

Hey Guys, We have a Nifi cluster that 5 days ago hung - the flow.xml.gz file got out of sync between the nodes due to prolonged connectivity issue. Ambari was also reporting a 98% JVM memory utilization (we have 32 Gigs). Once we resync'ed the flow.xml.gz file and restarted the nodes, the JVM memory dropped back down to 5%. Since then, the JVM memory has slowly climbed back up to 82% - which Ambari is warning with a color-coded orange. We don't have 'alot' of flows nor queued flowfiles (~300 flowfiles of less than 10k size), so I'm puzzled at the high JVM memory utilization. Any help diagnosing this issue would be greatly appreciated. ... View more

To whom it may concern: I am attempting to encrypt sensitive processor properties with the following snippet from my nifi.properties file: nifi.sensitive.props.key=1756eb0b-4eb3-46d6-98a4-a350b46c7459 nifi.sensitive.props.key.protected= nifi.sensitive.props.algorithm=PBEWITHMD5AND256BITAES-CBC-OPENSSL nifi.sensitive.props.provider=BC nifi.sensitive.props.additional.keys=my_secret I restarted Nifi but the value of the my_secret attribute remains unencrypted in flow.xml.gz. I've modified the value of my_secret several times but it is still saved in cleartext. Any help with this would be greatly appreciated. In addition, does anyone know what the value of "BC" means for the nifi.sensitive.props.provider key? Equivalently, anyone know where I can get a list of default sensitive properties? ... View more
