[jira] [Updated] (HDFS-15727) RpcQueueTimeAvgTime of the NameNode
increases after it becomes StandBy
[ https://issues.apache.org/jira/browse/HDFS-15727?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aihua Xu updated HDFS-15727:
----------------------------
Description:
RpcQueueTimeAvgTime of the NameNode on port 8020 (the client RPC calls) increases after it becomes StandBy. It will get resolved after it gets restarted. Seems there is something incorrect about this metrics.
See the following graph, the NameNode becomes StandBy at 10:13 while RpcQueueTimeAvgTime increases instead.
