Subject [jira] [Commented] (HBASE-14888) ClusterSchema: Add Namespace Operations
Date Wed, 06 Jan 2016 05:51:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14888?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15085023#comment-15085023

Anoop Sam John commented on HBASE-14888:
----------------------------------------

{quote}
This patch changes the semantic around namespace create/delete/modify when coprocessor asks
that the invocation be by-passed. Previous the by-pass was done silently -- the method would
just return with no indication as to whether by-pass route had been taken or not.  This patch
adds throwing of a BypassCoprocessorException which is thrown if we have been asked to bypass
a call.

Normally when the CP pre hook says to bypass, we bypass the actual op. The DML ops are like
that. DDL op when checked, the createTable seems just not considering the value at all. The
addColumn seems bypassing the add op.  How can we have a consistent behavior?

> Add in a ClusterSchema Interface. It will have all API for all cluster manipulation;
adding namespaces, tables, amending column families, etc. The idea is to gather up our mess
and put it all behind a tidy API that all works the same way whatever you changing returning
a Future to wait on and behind the scenes driving Procedures.
> This patch does namespace operations first.
