---------------------------------
Summary: RBF: AccessControlException is counted as proxy failure
Key: HDFS-16005
URL: https://issues.apache.org/jira/browse/HDFS-16005
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs
Reporter: Fengnan Li
Assignee: Fengnan Li
We are using ProxyOpCommunicateFailure as a metric for monitoring Router's
performance. However we recently noticed that when some clients try to access
files they don't have access to in Namenode. AccessControlException thrown from
Namenode was counted in this metric.
In our understanding ProxyOpCommunicateFailure is used as network/hardware
failure between Router and Namenode instead of the communication failure due
to client side.
