> org.apache.hadoop.hdfs.server.federation.fairness.StaticRouterRpcFairnessPolicyController#validateCount
> When dfs.federation.router.handler.count is lessthan the total dedicated
> handlers for all NS, then error message shows 0 & -ve values in error
> message, instead can show the actual configured values.
> Current message is : "Available handlers -5 lower than min 0 for nsId nn1"
> This can be changed to: "Configured handlers
> ${DFS_ROUTER_HANDLER_COUNT_KEY}=10 lower than min 15 for nsId nn1", where 10
> is hander count & 15 is sum of dedicated handler count.
