Subject [jira] [Commented] (HBASE-18600) Provide a method to disable the Short-Circuit HTable in coprocessor
Date Tue, 15 Aug 2017 16:56:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18600?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16127523#comment-16127523

Anoop Sam John commented on HBASE-18600:
----------------------------------------

Why we need this?  What is the need to avoid the short circuit?  Whether short circuit or
not should be abstracted out from the CP user. (IMO)

> HBASE-9534: Allow coprocessors accessing an HTable to short-circuit access to the local
HRegionServer, rather than requiring the usual RPC path. And it only worked for RegionCoprocessorEnvironment.
This issue add a new method for RegionCoprocessorEnvironment.  getShortCircuitTable method
is used to get a  short-circuit access HTable. And getTable method is used to get a normal
table.
