Hi, i have a problem using tableau with hadoop. I can connect to Clouder Hadoop on desktop, but when i publish the dashboard to server, it went error :Error "Unable to connect to the ODBC Data Source (...) [Cloudera][Hardy] (34) Error from Hive: connect() failed: errno =…
It says "Blocked ports preventing communication between Tableau Server and the Cloudera database."
My question is that if the server can't access hadoop, must i publish the data source and dashboard together? can this be auto triggered daily(the data is updated daily)?
I have done some research, pentaho tde plugin seems to be possible.So how do you guys solve this problem?
Do you have all the correct drivers installed on server? Does the server have direct access to the server? You could try running desktop from the server machine to verify connectivity is happening there as well.
