---------------------------------------
Summary: testdata loading should reuse TPCH/TPCDS local data if
they exist
Key: IMPALA-11124
URL: https://issues.apache.org/jira/browse/IMPALA-11124
Project: IMPALA
Issue Type: Improvement
Components: Infrastructure
Reporter: Quanlong Huang
Assignee: Quanlong Huang
When loading testdata for TPC-H/TPC-DS, we first run a preload script to
generate local data, and then upload them to HDFS to be used by Hive. It's
time-consuming to run the preload script in large scale factors (e.g. 30). We
should reuse them if they exist.
