-----------------------------------
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}
