Hello!
I am trying to run some experiments using a VM and I choose an A6 instance (4 cores, 28GB, Intel Xeon processor) which shows that there are only 4 physical cores and no hyperthreading (therefore 4 logical processors).
I have also built a HDInsight cluster with an A6 instance datanode and namenodes. I connected through the remote desktop and checked for the processors available through commandline and got 4 cores and 4 Logical processors. Yet when I run my application on the cluster and check the Hadoop Yarn Status web UI for the nodes that are up and running, there is a section under cluster metrics that says "VCores Available: 8".
Can anyone clarify why there is a discrepancy seen in the cluster?
Thank you!
