Tao Jie commented on YARN-5697:
-------------------------------
When I was trying to parse command line in RMAdminCLI by CliParser, I found
that existing acceptable command line logic is not so restrict.
eg:
{{yarn rmadmin -addToClusterNodeLabels -directlyAccessNodeLabelStore label1}}
is acceptable, however when using CLIParser to parse this cmd line, *label1*
would be parsed as argument of option *-directlyAccessNodeLabelStore* rather
than *-addToClusterNodeLabels*. Actually it makes more sense.
Same situation in cmd {{-removeFromClusterNodeLabels <label1,label2,label3>
(label splitted by ",")}} and {{-replaceLabelsOnNode \[-failOnUnknownNodes\]
<"node1\[:port\]=label1,label2 node2\[:port\]=label1,label2">}}
I am not sure if we should keep a loose logic to ensure compatibility(we should
consider *label1* is arg of *-directlyAccessNodeLabelStore* or
*-addToClusterNodeLabels*, both are ok) or make the command line logic more
accurate.
