Change subject: IMPALA-3739: Enable stress tests on Kudu

Patch Set 5:


It seems regardless of database, Kudu tables live in the same Kudu namespace. In order to
have TPCH and TPCDS data both loaded, at least one of the customer tables must have a different

But also, it's often convenient to have the same data of varying scales loaded on a stress
cluster for various experiments. Since we solve that problem by including the data scale in
the database name, I think we could solve these problems in Kudu by including the Impala database
as a prefix to each Kudu table.

Suggestion: prepend all the Kudu table names with the database name.
File testdata/datasets/tpcds/tpcds_kudu_template.sql:

PS5, Line 469: 'kudu.table_name'='customer',
Here's one kudu table called 'customer'. Can this (and others) be expanded to "{target_db_name}_customer"
File testdata/datasets/tpch/tpch_kudu_template.sql:

PS5, Line 185:   'kudu.table_name' = 'customer',
Here's another kudu table called "customer".
