RS already has this info cached and updated > when flush/compaction happens. Master can query and get instead of hitting > the namenode and caching. The larger the cluster becomes, the more costly it > becomes to get this information and more stale the cached information becomes. > This jira is only to add the API to regionserver. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
