[jira] [Commented] (ACCUMULO-2057) found two last locations for the
same extent
[ https://issues.apache.org/jira/browse/ACCUMULO-2057?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13853154#comment-13853154 ]
Eric Newton commented on ACCUMULO-2057:
---------------------------------------
Reproduced the problem after studying the logs:
* Create a tablet with a few mutations, flush it to give it a location.
* Shutdown the tserver hosting the tablet
* Split the tablet at its new location
* Compact the table: now it has two last locations!
