>                 Key: HBASE-3905
>                 URL: https://issues.apache.org/jira/browse/HBASE-3905
>             Project: HBase
>          Issue Type: Bug
>         Environment: Considering this function is open to users, this function should
validate the split key array. For example, I had tried creating a table with keys that had
duplicate entries. The master (sometimes) crashed with a KeeperException.
