Subject [jira] [Commented] (HBASE-17953) VerifyReplication should read all versions other than the latest version by default.
Date Mon, 24 Apr 2017 13:57:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17953?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15981179#comment-15981179

Ted Yu commented on HBASE-17953:
--------------------------------

For #1, there could be many versions for a cell. Reading all versions would incur additional
load on the server.

What's your use case ?

> Two  problems for VerifyReplication.java: 
> 1.  With the default versions ( DO NOT set --versions option) ,  we will  read the latest
version other than all version,  because Scan.maxVersions is 1.   Actuallly, I think we
should compare all version by default.
> 2.   In logFailRowAndIncreaseCounter() method ,  we should set  familly/TimeRange/maxVersions
attrs for a Get.
