Xu Cang reassigned HBASE-21338: ------------------------------- Assignee: Xu Cang > [balancer] If balancer is an ill-fit for cluster size, it gives little > indication > --------------------------------------------------------------------------------- > > Key: HBASE-21338 > URL: https://issues.apache.org/jira/browse/HBASE-21338 > Project: HBase > Issue Type: Sub-task > Components: Balancer > Reporter: stack > Assignee: Xu Cang > Priority: Major > Attachments: HBASE-21338.master.001.patch > > > See parent issue. Running balancer on a cluster where the max steps was way > inadequate, the balancer gave little to no indication that it was > ill-configured. In fact, it only logged its starting and then that there was > nothing to do though the cluster was obviously out-of-whack. > Ideally the balancer would complain when say the maxSteps limit is a small > fraction of what the cluster's calculated max steps are, or it would notice > that the balancer is making little progress on an imbalanced cluster and > shout. Can we set balancer configs w/o having to restart Master? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
