I build a 3 node cluster on 3 Ubuntu 18.04 device i builded CHD6.3.1 distrubition . I have complated setup and add few services as well . all wordked fine i used Cloudera Manager to build my cluster.
But when i tried to add some custom Services which is not in Cloudera Express edition like Nifi by following installitation (https://community.cloudera.com/t5/Community-Articles/Install-Nifi-on-one-node-using-Cloudera-Flow-Ma...) I realised that My Parcels giving errors ;
But i am able to run Kafka Service and Spark service . And from UI i get the response about those services. Till i want to use Nifi for load my local files to HDFS . Cant start Nifi .
Is parcels and requirements are problem here or am i missing something.
Also is Ubuntu Bionic is good to use for build a cluster. ?
Have a good time.
There are two ways to look at this:
If you followed the documentation, and found a limitation/bug, please log a support ticket. Either it will get fixed (or otherwise the doc should be updated).
That being said, though Ubuntu 18.04 is supported for CDH 6.3, I can tell that Ubuntu 18.04 is not supported for HDF (the Ambari deployment of NiFi etc.) so it is possible that a different OS will gain more attention.
If you are just trying things out, and want the easiest way, currently that is probably with Centos 7.6, as that is what most customers are using today.
Thank you for your response .
Any i also thougth same mostly i cant use :Hortonworks Sevices on Ubuntu Bionic so maybe would be better to run cluster all on Centos Devices . According to documentatiton there is no Parcels at all.
