Server: OS: CentOS 6.6 CDH 5.4.4 cluster with Cloudera manager - Version: Cloudera Express 5.4.3 (#258 built by jenkins on 201 git: 1139ffb081360fbbb1be8a19a87ca3c52ee4b1cf) Impala: impalad version 2.2.0-cdh5.4.4 RELEASE (build a13d3c6b203e79a284b509df821bffbe229e6dc3) Client: OS: Windows 7/8 client app: Tableau Desktop Latest, at the moment, Impala-ODBC driver - Tableau desktop: version 8/9. 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.
