-------------------------------------

             Summary: Validation message to be corrected in RBF FairnessPolicyController
                 Key: HDFS-15863
                 URL: https://issues.apache.org/jira/browse/HDFS-15863
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: rbf
    Affects Versions: 3.4.0
            Reporter: Renukaprasad C
            Assignee: Renukaprasad C


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.

Related to: HDFS-14090
