Dong Jiang commented on SPARK-13127: ------------------------------------ [~igozali], I think you are referring to this parquet ticket: https://issues.apache.org/jira/browse/PARQUET-686 The parquet ticket indicated the fix is in 1.9.0, so we still need Spark to upgrade parquet to 1.9.0 I have examined the parquet file generated by Spark 2.2, the string column doesn't have the min/max generated in the footer. I believe it is disabled. > Upgrade Parquet to 1.9 (Fixes parquet sorting) > ---------------------------------------------- > > Key: SPARK-13127 > URL: https://issues.apache.org/jira/browse/SPARK-13127 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.0.0, 2.0.1 > Reporter: Justin Pihony > > Currently, when you write a sorted DataFrame to Parquet, then reading the > data back out is not sorted by default. [This is due to a bug in > Parquet|https://issues.apache.org/jira/browse/PARQUET-241] that was fixed in > 1.9. > There is a workaround to read the file back in using a file glob (filepath/*). -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
