Subject [jira] [Commented] (HBASE-9116) Add a view/edit tool for favored node mappings for regions
Date Tue, 27 Aug 2013 18:03:52 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13751512#comment-13751512
] 

Jimmy Xiang commented on HBASE-9116:
------------------------------------

You already defined UpdateFavoredNodesRequest, why not use it? These two calls may divert
later on.  It is better to use different message so that it will be easier to maintain compatibility.

Why does this one take a RegionOpenInfo? At least, it doesn't need the zk node version right?

+message UpdateFavoredNodesRequest {
+  repeated OpenRegionRequest.RegionOpenInfo updateRegionInfo = 1;
+}

also fix the mappings if needed. Such a tool exists in the 0.89-fb branch. Will port it over
to trunk/0.95.
