> Hi,
> We are have a CDH 5.4.4 cluster and use Impala for add-hoc data analysis. We
> also use Tableau for data visualization. The Tableau connects to Impala using
> your ODBC driver. We experience several issues, but most important one is
> that sometimes (1 out of 10 queries) our queries fail for unknown issue. When
> we retry the issues is gone till the next occurrence. There is no info in the
> server and almost no info in the ODBC client log (see attachment). Actually
> the the only message that the client shows is logged in the ODBC log:
> Aug 10 14:02:43 ERROR 8284 Statement::SQLPrepareW: [Cloudera][ODBC] (10000)
> General error: Unexpected exception has been caught.
> Judging by this we suspect that this might be an ODBC driver issue in the
> client in the prepared statement logic.
