Hi community,
I am trying to understand the cluster and yarn usage graphs in cloudera manager.
On the one hand, the General Cluster chart informs that 100% of the cluster CPU was used, while the YARN chart only reports that only 33.99% was used.
Why YARN 33.99%, if spark jobs have been executed that use 100% of the cluster?
The memory has the same behavior, only 19.07% when they have been used around 99% in job executions
