    Description

      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.
