Compactions are also expensive to execute, especially on very large > tables. The balancer can do a good job trying to maintain locality (when > tuned properly), but it is not perfect. > This creates a less-than-desirable situation where it's a costly operation to > take a cluster with spotty poor locality (e.g. a small percentage of > regionservers with poor locality). > We already have this information available via the {{ClusterStatus}} proto. > We can easily write a shell command that can present regions which are > lacking a certain percentage of locality. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
