             Summary: java.io.EOFException Reached the end of stream - Reading Parquet from Swift
                 Key: SPARK-27570
                 URL: https://issues.apache.org/jira/browse/SPARK-27570
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.4.0
            Reporter: Harry Hough


I did see issue SPARK-25966 but it seems there are some differences as his problem was resolved after rebuilding the parquet files on write. This is 100% reproducible for me across many different days of data.

I get exceptions such as "Reached the end of stream with 750477 bytes left to read" during some read operations of parquet files. I am reading these files from Openstack swift using openstack-hadoop 2.7.7 on Spark 2.4.

 
{code:java}
    val engagementDS = spark
      .read
      .parquet(createSwiftAddr("engagements", folder))
      .where("engtype != 0")
      .where("engtype != 1000")
      .groupBy($"accid", $"sessionkey")
      .agg(collect_list(struct($"time", $"promoid", $"engtype", $"pageid", $"abtestid")).as("engagements"))

{code}
The above gives the error 100% of the time.
{code:java}
    val engagementDS = spark
      .read
      .parquet(createSwiftAddr("engagements", folder))
      .count
{code}
This works correctly as well as doing a .show(false)
{code:java}
    val engagementDS = spark
      .read
      .parquet(createSwiftAddr("engagements", folder))
      .groupBy($"accid", $"sessionkey")
      .agg(collect_list(struct($"time", $"promoid", $"engtype", $"pageid", $"abtestid")).as("engagements"))
      .show(false)
{code}
Works correctly.
{code:java}
    val engagementDS = spark
      .read
      .parquet(createSwiftAddr("engagements", folder))
      .where("engtype != 0")
      .count
{code}
The above code works but if I do .show(false) instead of count it breaks with the reached end of stream error.
{code:java}
engagementDS.select($"engtype").where("engtype != 0").where("engtype != 1000").show(false)

{code}
The above also works correctly.

Even if I'm doing something incorrectly this seems like a very strange error message :)
