Xiaobing Zhou commented on HDFS-11038: -------------------------------------- The test failure is irrelevant to the patch. I marked it in HDFS-10406. > DiskBalancer: support running multiple commands under one setup of disk > balancer > -------------------------------------------------------------------------------- > > Key: HDFS-11038 > URL: https://issues.apache.org/jira/browse/HDFS-11038 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: balancer & mover > Reporter: Xiaobing Zhou > Assignee: Xiaobing Zhou > Attachments: HDFS-11038.000.patch, HDFS-11038.001.patch > > > Disk balancer follows/reuses one rule designed by HDFS balancer, that is, > only one instance is allowed to run at the same time. This is correct in > production system to avoid any inconsistencies, but it's not ideal to write > and run unit tests. For example, it should be allowed run plan, execute, scan > commands under one setup of disk balancer. One instance rule will throw > exception by complaining 'Another instance is running'. In such a case, > there's no way to do a full life cycle tests which involves a sequence of > commands. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
