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, 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
