Subject [jira] [Commented] (HBASE-8504) HTable.getRegionsInRange() should provide a non-cached API
Date Wed, 08 May 2013 02:03:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13651549#comment-13651549

chunhui shen commented on HBASE-8504:
-------------------------------------

I think the caller of HTable#getRegionsInRange should always handle the case which the cache
is outdated.
The region location may be wrong even if we get it through non-cached API because of region-move
or region-split

> getRegionsInRange() calls getRegionLocation() without reloading it. It will return wrong
result if the cache is outdated due to region split. If the cost of always reloading isn't
significant, we should consider doing that by default. Otherwise, let's have an API for getRegionsInRange()
that forces a reload.
