----------------------------------------
Summary: "numFiles" in the explain plan should always reflect the
files read.
Key: DRILL-4074
URL: https://issues.apache.org/jira/browse/DRILL-4074
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.3.0
Reporter: Rahul Challapalli
git.commit.id.abbrev=e78e286
When the planner decides to read a whole directory (with more than one file),
the numFiles attribute in the explain plan output gives "1" which is wrong. It
should instead give the total no of files within the directory.
Our extended tests have quite a few partition pruning tests which rely on this
field in the plan.
