-------------------------------
Summary: Nested column pruning: fix issue when selecting struct
field from array/map element (part 2)
Key: HIVE-15537
URL: https://issues.apache.org/jira/browse/HIVE-15537
Project: Hive
Issue Type: Sub-task
Components: Logical Optimizer
Affects Versions: 2.2.0
Reporter: Chao Sun
Assignee: Chao Sun
HIVE-15507 only addresses the issue of
{code}
SELECT arr[0].f FROM tbl
{code}
However, it didn't handle:
{code}
SELECT arr[0].f.g FROM tbl
{code}
In this case the current code will generate a path {{arr.g}}, which is wrong.
