> Allow file splitting in combination with row index generation
> -------------------------------------------------------------

> Key: SPARK-39634
> URL: https://issues.apache.org/jira/browse/SPARK-39634
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: Ala Luszczak

> Priority: Major
> Fix For: 3.5.0

>
> This issue is a follow up for SPARK-37980
> Because of a bug in parquet-mr
> https://issues.apache.org/jira/browse/PARQUET-2161 it is currently impossible
> to generate row indexes for parquet files if they are split into multiple
> pieces. Instead, each file must be read in a single task.
> Once the version of parquet-mr with the fix is included in Spark, we should
> remove the workarounds from the code (marked with this ticket number) from
> the code, so that parquet files are splittable even when the row indexes need
> to be generated.
