> Key: IMPALA-5542
> URL: https://issues.apache.org/jira/browse/IMPALA-5542
> Project: IMPALA
> Issue Type: Sub-task
> Components: Backend
> Affects Versions: Impala 2.10.0
> Reporter: Tim Armstrong
> Assignee: Zoltán Borók-Nagy
> Priority: Major
> Labels: parquet
> Fix For: Impala 3.1.0
>
>
> This is supported according to the Parquet spec
> (https://github.com/Parquet/parquet-format/blob/master/LogicalTypes.md#decimal)
> but wasn't widely used. For some reason Spark decided to start writing this
> out as the default (see SPARK-20297) so we will likely start seeing this at
> some point.
