Subject [jira] Created: (HBASE-739) HBaseAdmin.createTable() using old HTableDescription doesn't work
Date Thu, 10 Jul 2008 21:28:31 GMT
HBaseAdmin.createTable() using old HTableDescription doesn't work
-----------------------------------------------------------------

                 Key: HBASE-739
                 URL: https://issues.apache.org/jira/browse/HBASE-739
             Project: Hadoop HBase
          Issue Type: Bug
          Components: client
    Affects Versions: 0.2.0
            Reporter: Sebastien Rainville
            Priority: Minor


The following test case (see below) illustrate what used to work in branch 0.1 and that doesn't
anymore. testTruncateInTrunk() shows how I got it to work again. I get this error now when
trying the old code but using trunk:
