Jing Zhao updated HDFS-6229: ---------------------------- Status: Patch Available (was: Open) > Race condition in failover can cause RetryCache fail to work > ------------------------------------------------------------ > > Key: HDFS-6229 > URL: https://issues.apache.org/jira/browse/HDFS-6229 > Project: Hadoop HDFS > Issue Type: Bug > Components: ha > Affects Versions: 2.1.0-beta > Reporter: Jing Zhao > Assignee: Jing Zhao > Attachments: HDFS-6229.000.patch, retrycache-race.patch > > > Currently when NN failover happens, the old SBN first sets its state to > active, then starts the active services (including tailing all the remaining > editlog and building a complete retry cache based on the editlog). If a retry > request, which has already succeeded in the old ANN (but the client fails to > receive the response), comes in between, this retry may still get served by > the new ANN but miss the retry cache. -- This message was sent by Atlassian JIRA (v6.2#6252)
