[jira] [Commented] (ACCUMULO-2207) tablet extent overlaps
previously assigned
[ https://issues.apache.org/jira/browse/ACCUMULO-2207?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13875156#comment-13875156 ]
Eric Newton commented on ACCUMULO-2207:
---------------------------------------
This is a known issue. From the code:
{noformat}
// checking if this exact tablet is in any of the sets
// below is not a strong enough check
// when splits and fix splits occurring
{noformat}
> tablet extent overlaps previously assigned
