Subject [jira] [Commented] (CASSANDRA-6638) SSTableScanner can Skip Rows with vnodes
Date Thu, 30 Jan 2014 16:20:18 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6638?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13886726#comment-13886726

Tyler Hobbs commented on CASSANDRA-6638:
----------------------------------------

+1 on the patch with a minor nit: can you remove the "this will currently fail" comment and
mention 6638 in the new test?

> CASSANDRA-2524 added multiple range support to SSTableScanner, but it looks like there
is at least one case where keys can be skipped.  This can result in cleanup removing legitimate
keys.
> See the attached patch that adds a unit test to reproduce the case.
