Hi! I tried to use this setup for MariaDB - without success... i.e. my trial already failed at the CDC-Processor (with a dockerized NiFi and the org.mariadb.jdbc.Driver). Is MariaDB known to not work? PS: without the Distributed-Map-Cache-Client - it works (of course I don't get the table and column names - which I guess would be "more than just nice"... with the DMCC I get a JDBC error "creating binlog enrichment"

are you referring to the "hdfs client"? if so, yes. The Master also contains both, ambari-server as well as the ambari-agent.

Hi, for everyone experiencing the error in the screenshot... check if there is some hidden central user management system active - which deletes your users... Daniel

How can we deal with SECURED http connections? NiFi runs on: https://<ip>:8443 and I'm using SSL certificates for authentication

Using the PutHiveStreaming processor and a verified correct AVRO schema for our data - NiFi puts only NULL if hierarchical JSON is used as input. Example with our data below "Person" {
"Person":{
"Name": "A",
"Age": 23
}
}
will produce NULL in the Hive table: Name Age
NULL NULL While a "flat" JSON file, like: {
"Name": "A",
"Age": 23
} will actually put the data into our hive table: Name Age
A 23 Does anyone have a solution so we can use JSON levels/hierarchies? Thank you sincerely!

i wanted to let you know the result of our analysis: Qlik will use TEZ which considerably speeds up the request times - IF the SQL-statement is sufficiently complex! (i.e. use a count or sum command - as a dummy)

hive.execution.engine already is TEZ - we do not want MR due to its very very poor performance... the problem appears to be with Qlik...
