Subject [jira] [Commented] (HBASE-15044) Region normalization should be allowed when underlying namespace has quota
Date Tue, 29 Dec 2015 06:43:49 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15044?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15073550#comment-15073550

Heng Chen commented on HBASE-15044:
-----------------------------------

NamespaceAuditor#checkQuotaToSplitRegion()  not only check the quota, it also update the quota
info.
IMO we should NOT update quota info here,  what we need is one method only do check.  wdyt?

> Currently when namespace has quota, HMaster#normalizeRegions() skips the tables in the
namespace.
> However, performing region merge(s) wouldn't violate quota constraint.
> For region split, NamespaceAuditor#checkQuotaToSplitRegion() can be called to check whether
quota is about to be exceeded. If not, region split plan can still be executed.
