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

...currently we are using JOLT as to not confuse the hbase-processor with parent-child levels

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...

Hi, we have seen that only more complex (case, count,...) SELECT statements from Qlikview are being executed via TEZ. All settings in Ambari are set to use TEZ by default. Is this a Hortonworks issue? Thank you!
