Subject [jira] [Commented] (HBASE-11261) Handle splitting/merging of regions that have region_replication greater than one
Date Tue, 29 Aug 2017 18:17:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16145826#comment-16145826

Enis Soztutar commented on HBASE-11261:
---------------------------------------

The initial plan was to have the daughters refer to the parent replica until their own split
is complete, so that during the split, read availability is not affected since the readers
can go to the replica regions to read while the region is still splitting. However, as per
above, that seemed too-complex to keep references around, especially fixing these kind of
edge-cases would be pretty hard for HBCK, so I think we have simplified the approach. When
a split happens, meta is updated with entries about split daughter replicas, but as far as
I remember, there was not reason to do further changes in CJ for this.
