Yiqun Lin commented on HDFS-13478: ---------------------------------- [~elgoiri], I did a quick glance for the patch, some thoughts from me: * If we make decommission info as a separate table, that mean we will do the query operation for State Store from one time to twice. Does this will make any performance impact? * Looks like this patch is large. We could separate this into two parts: # Decommission Store APIs implementation (Seems HDFS-13478.000.patch is just doing on this). # Add checking logic in Router sever side and corresponding test for the decommission case. > RBF: Decommission subclusters from the federation > ------------------------------------------------- > > Key: HDFS-13478 > URL: https://issues.apache.org/jira/browse/HDFS-13478 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Íñigo Goiri > Assignee: Íñigo Goiri > Priority: Major > Attachments: HDFS-13478.000.patch > > > We have a subcluster in our federation that is for testing and is > missbehaving. This has a negative impact on the performance with operations > that go to every subcluster (e.g., renewLease() or setSafeMode()). -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
