We have a distributed Tableau environment and we are running a Hadoop cluster. We installed the Cloudera for Impala ODBC driver v.2.5.26 on all of the tableau servers and also had the users install it on their machines. We can see the databases, but they do not refresh and we alway get the error that "the data source is out of date. No workbooks are affected. Error unknown"
If I test the connection it succeeds. This is preventing us from keeping up to date on our reports. Please help!
