Hello Andrés, Yes we had a look at it, in fact it seems it's really solved with 2.7 with https://issues.apache.org/jira/browse/NIFI-14959. I add a look at the code fix provided and well it seems to concern really this partition by attribute. By the way, when we saw this defect, I tried another test. I create a dummy attributs and assign randomly a value 0 - 10 and then tried the partition load by this atrribute. This was even worst than the load balance strategy(I had less reccords processed than the third I had with load balace strategy). If it was the same kind of issue, I was expecting to have roughly the same amount of processed reccords. I say roughly because in this second test I had perhaps 10% of the reccords processed vs 33% with the load balance strategy. In addition, we are not big fans of pushing to our Prod right now a version (2.7.1) which has been released 3 days ago only.  That was why we were searching if someone else faced the issue or if someone else was using this version with load balance strategy without having issue. Just to try to narrow down where the issue comes from: nifi 2.4 or our platform. Anyway thank you very much for your answer Andrés,   Best regards,   Olivier   ... View more

Hi @yoonli As per my knowledge Cloudera will not support Standalone setup and supported types are YARN and Kubernetes.  For your error, you need to check kerberos setup for standalone cluster and try to run simple examples like SparkPi and see whether it is working or not. ... View more

Hello @Samya,  Thanks for joining our community.  That issue is happening because JSON_STORE format is VARCHAR(2), not VARIANT as required.  Something you can try is to add a ConvertRecord processor before the PutDatabaseRecord.  There, you can use a JsonTreeReader → JsonRecordSetWriter to reformat the content. In that way, the JSON_STORE field becomes a proper JSON object. Something like this👆 ... View more
