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.
