> Project: IMPALA
> Issue Type: Bug
> Components: Infrastructure
> Affects Versions: Impala 4.0.0
> Reporter: Riza Suminto

> single_node_perf_run.py has a required argument "scale". If scale > 1, the
> script runs fine. But if scale = 1 and load is true, the data loading script
> will fail due to missing dataset. This is becasue the preload script omit the
> scale number padding when creating dataset directory.

> ie., tpch scale 1 will create dataset dir "testdata/impala-data/tpch".
> On the other hand, generate-schema-statements.py will create template sql
> referring to "testdata/impala-data/tpch1".

> Consider creating symlink if scale factor = 1 in the preload script.
