-------------------------------
Hi [~Naganarasimha], [~sunilg]
I summarized the below issues i came across in 2.6 so far..And i will make
progress to see others. Thank you for your patience !
1) Node label exclusivity is not supported like below command
sudo -u yarn yarn rmadmin -addToClusterNodeLabels "c(exclusive=false)"
addToClusterNodeLabels: java.io.IOException: label name should only
contains
{0-9, a-z, A-Z, -, _} and should not started with {-,_}, now it
is=c(exclusive=false)
2) Node labels are supported only in Capacity Scheduler
3) Listing node labels are not supported like below command
sudo -u yarn yarn cluster --list-node-labels
Error: Could not find or load main class cluster
4) Assign Node Labels to Cluster Node
Not supported format - sudo -u yarn yarn rmadmin -replaceLabelsOnNode
"bb-node3=y"
Supported format - sudo -u yarn yarn rmadmin -replaceLabelsOnNode
"bb-node3,y"
> Add documentation for the Node Label features supported in 2.6

> 2.6 and general commands to use it. So it would be better to have
> documentation capturing what all is supported as part of 2.6
