I would like to understand the internal in / outs of Cloudera flow. How CM interacts with other components in the Hadoop stack ( HDFS / YARN/ IMPALA etc.), would like to know if there are any references material / documents which I can go through to enhance my knowledge in this area.
Appreciate any information in this regard.
You can find the overview of CM internals in this blog https://blog.cloudera.com/how-does-cloudera-manager-work and the details of health tests on each service in https://docs.cloudera.com/documentation/enterprise/latest/topics/cm_ht.html
