we would like to set up a Cloudera CDH 6.2.1 cluster
and we have an existing client edge node
with Apache Hadoop 2.6.0 and Apache Hive 2.2.1 from the Apache projects.
The question is that the above set up is "supported" by any means,
or the existing clients are incompatible with the cluster?
You need to distribute the Cloudera clients. HDP and Apache clients are not supported.
