Ryan Blue reopened PARQUET-188:
-------------------------------
Reopening to track the spec update.
> Parquet writes columns out of order (compared to the schema)
> ------------------------------------------------------------
>
> Key: PARQUET-188
> URL: https://issues.apache.org/jira/browse/PARQUET-188
> Project: Parquet
> Issue Type: Bug
> Components: parquet-mr
> Reporter: Colin Marc
> Assignee: Ryan Blue
> Fix For: parquet-mr_1.6.0
>
>
> When building from master, parquet seems to write row groups with the columns
> in arbitrary orders, not in the same order as the schema. This appears to
> happen regardless of the OutputFormat or WriteSupport used.
> This breaks implementations that assume the columns will be in a specific
> order, in particular impala.
