[jira] [Commented] (PARQUET-1039) PARQUET-911 Breaks Arrow

["Phillip Cloud (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PARQUET-1039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16060408#comment-16060408 ] 

Phillip Cloud commented on PARQUET-1039:
----------------------------------------

Now I'm not sure that PARQUET-911 is the culprit here. I think PARQUET-911 exposed a possible bug in that test, which is that there are duplicate column names in the call to {{pa.Table.from_arrays}}. I'm still not sure why the data would have ever compared equal in repeated testing. I'm going to get to the bottom of this tomorrow.

> When comparing the results of a parquet file to expected data, after PARQUET-911, a single arrow test is failing: {{pyarrow/tests/test_parquet.py::test_date_time_types}}. It's not entirely clear how PARQUET-911 affects this code, but the data in {{time32}} and {{time64}} columns do not compare equal.
