    tableau server can't access hadoop

    lei yu

      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?
