--------------------------------------
Summary: Compressed HDFS files processing with spark failing from
version Spark 2.2.x with error: "java.lang.IllegalArgumentException:
requirement failed: length (-1) cannot be negative"
Key: SPARK-27239
URL: https://issues.apache.org/jira/browse/SPARK-27239
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.4.0, 2.3.3, 2.3.2, 2.3.1, 2.3.0, 2.2.3, 2.2.2, 2.2.1
Reporter: Rajesh Kumar K
>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.

+Below is the code snippet which caused this issue.+
** {color:#FF0000}require(length >= 0, s"length ($length) cannot be
negative"){color} // This validation caused the issue.
{code:java}
// code placeholder
org.apache.spark.rdd.InputFileBlockHolder - spark-core
def set(filePath: String, startOffset: Long, length: Long): Unit = {
require(filePath != null, "filePath cannot be null")
require(startOffset >= 0, s"startOffset ($startOffset) cannot be negative")
require(length >= 0, s"length ($length) cannot be negative")
inputBlock.set(new FileBlock(UTF8String.fromString(filePath), startOffset,
length))
}
{code}
+Steps to reproduce the issue.+
I am able to reproduce this issue from spark-shell with below steps.
import org.apache.hadoop.mapred.FileInputFormat
import org.apache.hadoop.fs.Path
FileInputFormat.setInputPaths(hadoopConf, new
Path("/output656/part-r-00000.gz"))
val records = sc.hadoopRDD(hadoopConf*,*
classOf[com.platform.custom.storagehandler.INFAInputFormat]*,*
classOf[org.apache.hadoop.io.LongWritable],
classOf[org.apache.hadoop.io.Writable])
records.count()
