Subject [jira] [Commented] (HBASE-11567) Write bulk load COMMIT events to WAL
Date Sat, 07 Feb 2015 00:35:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11567?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14310302#comment-14310302

Enis Soztutar commented on HBASE-11567:

Can you change this following: 
+    WALKey key = new WALKey(info.getEncodedNameAsBytes(), tn);

    // we use HLogKey here instead of WALKey directly to support legacy coprocessors.
    WALKey key = new HLogKey(info.getEncodedNameAsBytes(), tn);
The other similar methods in WALUtil (writeCompactionMarker) does that. Other than that +1.

I have checked the PB refactor I was talking about earlier. It seems it is compatible in wire
format, and I also tried manually serializing and deserializing with this change.

> Similar to writing flush (HBASE-11511), compaction(HBASE-2231) to WAL and region open/close
(HBASE-11512) , we should persist bulk load events to WAL.
> This is especially important for secondary region replicas, since we can use this information
to pick up primary regions' files from secondary replicas.
> A design doc for secondary replica replication can be found at HBASE-11183.
