Xiangyi Zhu updated HDFS-16421: ------------------------------- Summary: RouterRpcFairnessPolicyController remove ConcurrentNS (was: RouterRpcFairnessConstants remove ConcurrentNS ) > RouterRpcFairnessPolicyController remove ConcurrentNS > ------------------------------------------------------ > > Key: HDFS-16421 > URL: https://issues.apache.org/jira/browse/HDFS-16421 > Project: Hadoop HDFS > Issue Type: Improvement > Components: rbf > Affects Versions: 3.4.0 > Reporter: Xiangyi Zhu > Assignee: Xiangyi Zhu > Priority: Major > > When using the RouterRpcFairnessConstants strategy, if the NamNode rpc is > slow or does not respond, it is easy to use up the concurrent available > handlers, and the client will not be able to renewLease normally. > I think CONCURRENT_NS can be removed. When there is an rpc of CONCURRENT, we > traverse each NS to apply for the corresponding Handler, instead of just > applying for one Handler like CONCURRENT. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
