John Kew commented on IMPALA-2200: ---------------------------------- That capability I mentioned is currently undocumented on the Tableau side ( fixing that ), but it suppresses all prepared queries for the data source and we use it with a number of hive-based datasources.

Hashmi > Priority: Minor > Labels: impala, odbc > Attachments: SimbaImpalaODBC_driver.log > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
