Subject [jira] [Commented] (CASSANDRA-5858) Add a shuffle dtest
Date Thu, 29 Aug 2013 17:42:57 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5858?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13753858#comment-13753858

Daniel Meyer commented on CASSANDRA-5858:
-----------------------------------------

As a first step I will add shuffle to the upgrade_through_versions_test.  In this test we
are currently enabling vnodes when we upgrade to 1.2; however, we are not running shuffle
afterwords.

In addition to this I would like feedback concerning what kinds of tests are needed.  Preliminary
test plan includes:
1)Add large number of rows with cassandra-stress, run shuffle and ensure the data can be read
back.
2)Run cassandra-stress followed by shuffle and ensure the 'owned %' for the nodes is within
some acceptable error.
3)Adding/Removing nodes followed by a shuffle.  Run cassandra-stress to ensure data is readable
and measure balance with 'owned %' for each node.
