Subject [jira] [Commented] (HBASE-15228) Add the methods to RegionObserver to trigger start/complete restoring WALs
Date Wed, 18 May 2016 05:59:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15228?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15288488#comment-15288488
] 

Anoop Sam John commented on HBASE-15228:
----------------------------------------

Normally the pre hooks honor bypass.  See preWALRestore() and its usage.  Do we want to do
same with new pre hook also?
Also do we need to pass WAL detail also to hooks? I see WAL reader is private and not exposed.

> In our use case, we write indexes to a index table when restoring WALs. We want to trigger
start/complete restoring WALs for initial and end processing for writing indexes.
