Josh Elser commented on HBASE-16961: ------------------------------------ bq. Regardless of the usefulness, the extra columns missing on list_quota_violations might be due to an internal change (RS's used to only see the violation policy or nothing – they see the full snapshot now). bq. Suggestion for filtering options: Actually, thinking about this more, I like this idea. Can also add a {{REGIONSERVER}} option to differentiate getting the state from the quota table and asking a RS for its view. One less command, more functionality on the one command.

Region size > is computed by RegionServers and sent to the Master. The Master inspects the > sizes of Regions, rolling up to table and namespace sizes. Defined quotas in > the quota table are evaluated given the computed sizes, and, for those > tables/namespaces violating the quota, RegionServers are informed to take > some action to limit any further filesystem growth by that table/namespace. > Discuss: > https://lists.apache.org/thread.html/66a4b0c3725b5cbdd61dd6111c43847adaeef7b7da5f4cd045df30ef@%3Cdev.hbase.apache.org%3E > Design Doc: > http://home.apache.org/~elserj/hbase/FileSystemQuotasforApacheHBase.pdf or > https://docs.google.com/document/d/1VtLWDkB2tpwc_zgCNPE1ulZOeecF-YA2FYSK3TSs_bw/edit?usp=sharing -- This message was sent by Atlassian JIRA (v6.3.15#6346)
