Phabricator commented on HBASE-5515: ------------------------------------ lhofhansl has commented on the revision "HBASE-5515 [jira] Add a processRow API that supports atomic multiple reads and writes on a row". Looks good. INLINE COMMENTS src/main/java/org/apache/hadoop/hbase/coprocessor/RowProcessor.java:72 What does this do on top of a "normal" scanner? Is it that a RowProcessor implementation does not have access to the HRegion and hence cannot get a scanner? (One more reason for using coprocessor endpoints, as they can just get the HRegion through the coprocessor environment. :) ) I.e. the coprocessor can just call HRegion.getScanner(scan).
