I've got Tableau desktop 10.0 on my Windows7 OS configured with Cloudera Hadoop Impala connector trying to extract data from Impala sql query.
The connector I installed is ImpalaODBC Connector 2.6.0 with impala 2.7.0 jdbc service.
I tried to extract about 20 million data , each row has 20 columns.
The desktop gives a “”[Cloudera][ImpalaODBC](120) Error while retrieving data from in Impala: [08S01]: ETIMEDOUT “” EXCEPTION
Does anyone have advice for investigating or fixing this?
