[jira] [Commented] (HBASE-11608) Add synchronous split

    [ https://issues.apache.org/jira/browse/HBASE-11608?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14082941#comment-14082941 ] 

Nick Dimiduk commented on HBASE-11608:
--------------------------------------

I was thinking of the case when the connection between client and RS is dropped. When that happens, the result of the split operation can not be discovered, other than by side-effect. There are many other "meta" operations like this where the client cannot know a result except by side-effect. As I understand it, resolving these kinds of issues in a general case is the primary motivation behind HBASE-5487.
