[jira] [Updated] (CASSANDRA-12917) Increase error margin in SplitterTest

     [ https://issues.apache.org/jira/browse/CASSANDRA-12917?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Marcus Eriksson updated CASSANDRA-12917:
----------------------------------------
       Resolution: Fixed
    Fix Version/s:     (was: 3.11.x)
                   4.0
                   3.11.2
           Status: Resolved  (was: Ready to Commit)

ah thanks for the ping

committed the lazy approach since this I don't think this has failed for a long time (and bumping the margin should make it "never" fail...).

> SplitterTest is a randomized test - it generates random tokens and splits the ranges in equal parts. Since it is random we sometimes get very big vnodes right where we want a split and that makes the split unbalanced
> Bumping the error margin a bit will avoid these false positives.
