Subject [jira] [Commented] (HBASE-9466) Read-only mode
Date Tue, 10 Sep 2013 20:31:54 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13763471#comment-13763471

Jean-Daniel Cryans commented on HBASE-9466:
-------------------------------------------

It is set here: https://github.com/apache/hbase/blob/trunk/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java#L621

Then we check the write state when doing operations that can mutate data.

> Can we provide a read-only mode for a table? write to the table in read-only mode will
be rejected, but read-only mode is different from disable in that:
> 1. it doesn't offline the regions of the table(hence much more lightweight than disable)
> 2. it can serve read requests
> Comments?
