Cloudera Hadoop internal workings

wert_1311 — Thu, 27 Feb 2020 04:37:17 GMT

Hello,

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.

Regards

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

@wert_1311,

Venkat's first link seems to be broken, I will share again here:
https://blog.cloudera.com/how-does-cloudera-manager-work/

And official doc is here:
https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cloudera_manager.html

I also wrote one basic blog on Cloudera Management services, not sure if it can help:

Cheers
Eric
