--------------------------------------
Summary: CLONE - Processing Compressed HDFS files with spark
failing with error: "java.lang.IllegalArgumentException: requirement failed:
length (-1) cannot be negative" from spark 2.2.X
Key: SPARK-27259
URL: https://issues.apache.org/jira/browse/SPARK-27259
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.2.1, 2.2.2, 2.2.3, 2.3.0, 2.3.1, 2.3.2, 2.3.3, 2.4.0
Reporter: Simon poortman
>From spark 2.2.x versions, when spark job processing any compressed HDFS files
>with custom input file format then spark jobs are failing with error
>"java.lang.IllegalArgumentException: requirement failed: length (-1) cannot be
>negative", the custom input file format will return the number of bytes length
>value as -1 for compressed file formats due to the compressed HDFS file are
>non splitable, so for compressed input file format the split will be offset as
>0 and number of bytes length as -1, spark should consider the bytes length
>value -1 as valid split for the compressed file formats.
We observed that earlier versions of spark doesn’t have this validation, and
found that from spark 2.2.x new validation got introduced in the class
InputFileBlockHolder, so spark should accept the number of bytes length value
-1 as valid length for input splits from spark 2.2.x as well.
