Subject [jira] [Commented] (HBASE-8219) Align Offline Merge with Online Merge
Date Mon, 01 Apr 2013 04:09:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13618597#comment-13618597

chunhui shen commented on HBASE-8219:

bq.The second and third calls wouldn't have effect because server is null.So if we expose
createMergedRegion() as public method, we can call it directly.
merged.openHRegion(reporter) is also called in RegionMergeTransaction#openMergedRegion.

bq.Maybe we can also implement hbase shell bindings for online one. 
Shell command of online region is already done(HBASE-8189)

1.We should fix the snapshot break caused by offline merge now
2.Do some easy alignment about the code of online merge and offline merge, since we plan to
remove offline merge in a futuer moment

> We should remove the offline one, or align it to the online code.
> Most of the offline code in HRegion.merge() can be replaced with the one in RegionMergeTransaction,
used by the online version.
