-------------------------------
Summary: Nested column pruning: don't prune paths when a SerDe is
used only for serializing
Key: HIVE-15499
URL: https://issues.apache.org/jira/browse/HIVE-15499
Project: Hive
Issue Type: Sub-task
Components: Serializers/Deserializers
Reporter: Chao Sun
Assignee: Chao Sun
In {{FileSinkOperator}}, a serializer is created to write output data. When
initializing it we should not read the
{{ColumnProjectionUtils.READ_NESTED_COLUMN_PATH_CONF_STR}} property since this
is only used for the read path, and the path may not match the schema for the
output table (for instance, in the case of insert).
