Subject [jira] [Created] (HIVE-15499) Nested column pruning: don't prune paths when a SerDe is used only for serializing

-------------------------------

             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).
