Change subject: IMPALA-15126: Fix NullPointerException for STRUCT.* expansion on masked tables ...................................................................... IMPALA-15126: Fix NullPointerException for STRUCT.* expansion on masked tables When a table has a column-masking policy, queries are rewritten to read from a table-masking view and re-analyzed. Expanding a struct that contains a nested collection - via STRUCT.* or SELECT * with EXPAND_COMPLEX_TYPES=true - built the collection's relative path with Path.createRelPath(), which did not carry the path's table-masking marker. The collection was therefore rooted at the underlying table's tuple, which is registered only inside the masking view's analyzer, so CollectionTableRef.analyze() -> Analyzer.findAnalyzer() returned null and threw a NullPointerException. Path.createRelPath() now propagates the pre-masking path to the derived relative path, so a collection reached through struct expansion roots at the masking view's tuple in the current query block (matching how directly selected masked collections already resolve).
