I have signed certs for my servers from a CA and want to enable SSL on NiFi. Is NiFi CA service required to enable SSL if I already have signed certs?

I launched cloudbreak deployer in azure using the quick start option. This option allowed me to set admin username and password. How do I change the password?

Our browser requires interacting with only signed certificates. Does NiFi CA generate self signed or signed certs? I assume it is self signed and not integrated with a real certificate authoruity. But not sure. Feedback appreciated.

ORC and Parquet are optimized for OLAP queries since only a subset of the columns from the source tables are used. Avro and other row based perform better if you have to look at entire record. Hav from one datatype to another (multi-hive table approach) is a common practice to determine which format performs the best for your use case. Performance test all three types is my recommendation. There is no one size fits all.

accessKey=<access key>
secretKey=<security key>
