Íñigo Goiri commented on HDFS-14284: ------------------------------------ {quote} do we have any advantage of having a RouterIOException, rather than directly calling super(msg + "from" + routerId); in the new constructors? {quote} It is easier to handle from the client side. If we know is a subtype of RouterIOException we can just do getRouterId() instead of having to parse messages. I think is a better design overall. > 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 > Assignee: hemanthboyina > Priority: Major > Attachments: HDFS-14284.001.patch > > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
