Subject [jira] [Commented] (HBASE-11936) IsolationLevel must be attribute of a Query not a Scan
Date Wed, 10 Sep 2014 22:00:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14129204#comment-14129204

Andrew Purtell commented on HBASE-11936:
----------------------------------------

Java binary compatibility supports moving a method upward in the class hierarchy, provided
a forwarding method is left in its place. Searched around for "java moving method upward".

> The Get operation is implemented in HBase as a Scan. The default isolation level for
Scan is READ_COMMITTED. The API to change the isolation level is part of Scan class and there
is no way for Get operation to change this from default. We should move this API up to Query
(which is a parent of both: Scan and Get).
