In what way did it make things worse? When you tried -q, did you drop the "-f user.sql" part off of your command line? Did you add "show databases" right after -q?

This is a known issue, but I havent yet seen it without multiple concurent Impala writers. (I have been able to repro it both in the same impalad and in different impalads.) https://issues.cloudera.org/browse/IMPALA-2423 Is there only a single writer using a single impalad at the time?

I asked around, and somebody knew somebody who asked Simba. They said: "There shouldn't be a limitation on the number of rows imposed by the driver, although there is a statement attribute for limiting the number of rows to return (SQL_ATTR_MAX_ROWS). If there are further issues, can you please tell the customer to enable logging through ODBC Administrator and send a zip file of the captured driver logs?"
