Hi Guys, I'm new to Cloudera. There is a setup od CDH v5.6 and Cloudera Manager v5.6 I have a requirement to upgrade Hue from 3.9 to 4.1, so I've decided to upgrade CDH and Cloudera Manager to 5.14. Do I need to upgrade all the underlying components like hive, impala, spark, hdfs etc. after upgrading CDH?? Please let me know. Thank You Shiva

CDH is a collection of components. When you upgrade CDH, you actually upgrade all of them:
