----------------------------------
Summary: Improved usability of classpath sample data files
Key: DRILL-4712
URL: https://issues.apache.org/jira/browse/DRILL-4712
Project: Apache Drill
Issue Type: Improvement
Reporter: Paul Rogers
Priority: Minor
Drill includes sample data in jar files (such as Foodmart). Drill provides the
"cp" data source to access the data:
> SELECT * FROM cp.`customer.json`;
However, the cp data source is somewhat broken:
> USE cp;
> SHOW FILES;
Error: SYSTEM ERROR: UnsupportedOperationException: ClassPathFileSystem doesn't
currently support listing files.
Modify the cp data source to support listing files. Since files are on the
classpath, any search would include a vast number of internal Java class files
and resource files.
To avoid that problem, perhaps move the sample data into a specific folder such
as /foodmart. Then, we could create a specialized cp data source
("cp.foodmart") that lists only that one folder.
