Subject [jira] [Created] (HBASE-3905) HBaseAdmin.createTableAsync() should check for invalid split keys.
Date Fri, 20 May 2011 00:18:47 GMT
HBaseAdmin.createTableAsync() should check for invalid split keys.
------------------------------------------------------------------

                 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.
