-----------------------------------

             Summary: Creating a Kudu table via JDBC fails with "IllegalArgumentException"
                 Key: IMPALA-9486
                 URL: https://issues.apache.org/jira/browse/IMPALA-9486
             Project: IMPALA
          Issue Type: Bug
    Affects Versions: Impala 3.2.0
            Reporter: Grant Henke


A Kudu user reported that though creating tables via impala shell or Hue, when using an external tool connected via JDBC the create statement fails with the following:
{noformat}
[ImpalaJDBCDriver](500051) ERROR processing query/statement. Error Code: 0, SQL state: TStatus(statusCode:ERROR_STATUS, sqlState:HY000, errorMessage:ImpalaRuntimeException: Error creating Kudu table 'impala::default.foo' CAUSED BY: IllegalArgumentException: table owner must not be null or empty ), Query: …
{noformat}
 

When debugging the issue further it looks like the call to set the owner on the Kudu table should not be called if an owner is not explicitly set:

[https://github.com/apache/impala/blob/497a17dbdc0669abd47c2360b8ca94de8b54d413/fe/src/main/java/org/apache/impala/service/KuduCatalogOpExecutor.java#L252]

 

A possible fix could be to guard the call with _isSetOwner_:
{code:java}
if (msTbl.isSetOwner()) { 
   tableOpts.setOwner(msTbl.getOwner()); 
}
{code}
