[jira] [Commented] (HBASE-10352) Region and RegionServer changes for opening region replicas, and refreshing store files

    [ https://issues.apache.org/jira/browse/HBASE-10352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13896815#comment-13896815 ] 

Devaraj Das commented on HBASE-10352:
-------------------------------------

LGTM overall. One nit is that, given the considerations in HBASE-10347 about names, should we make this patch adhere to that - "primary" to "default" and "secondary" to "replica"...

> Region replicas should be opened in read-only mode, and the "replica" mode so that they serve queries from the primary regions' files. 
> This jira will also capture periodic refreshing of the store files from the secondary regions so that they can get flushed and compacted files according to the "region snapshots" section in the design doc for the parent jira.
