Subject [jira] [Created] (HDFS-14284) RBF: Log Router identifier when reporting exceptions
Date Fri, 15 Feb 2019 20:26:00 GMT
Íñigo Goiri created HDFS-14284:
----------------------------------

             Summary: RBF: Log Router identifier when reporting exceptions
                 Key: HDFS-14284
                 URL: https://issues.apache.org/jira/browse/HDFS-14284
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Íñigo Goiri


The typical setup is to use multiple Routers through ConfiguredFailoverProxyProvider.
In a regular HA Namenode setup, it is easy to know which NN was used.
However, in RBF, any Router can be the one reporting the exception and it is hard to know
which was the one.
We should have a way to identify which Router/Namenode was the one triggering the exception.
This would also apply with Observer Namenodes.
