Simon poortman created SPARK-27259: -------------------------------------- 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. +Below is the stack trace.+ Caused by: java.lang.IllegalArgumentException: requirement failed: length (-1) cannot be negative at scala.Predef$.require(Predef.scala:224) at org.apache.spark.rdd.InputFileBlockHolder$.set(InputFileBlockHolder.scala:70) at org.apache.spark.rdd.HadoopRDD$$anon$1.<init>(HadoopRDD.scala:226) at org.apache.spark.rdd.HadoopRDD.compute(HadoopRDD.scala:214) at org.apache.spark.rdd.HadoopRDD.compute(HadoopRDD.scala:94) at org.apache.spark.rdd.RDD.computeOrReadCheckpoint(RDD.scala:324) at org.apache.spark.rdd.RDD.iterator(RDD.scala:288) at org.apache.spark.scheduler.ResultTask.runTask(ResultTask.scala:87) at org.apache.spark.scheduler.Task.run(Task.scala:109) at org.apache.spark.executor.Executor$TaskRunner.run(Executor.scala:345) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) +Below is the code snippet which caused this issue.+ ** {color:#ff0000}require(length >= 0, s"length ($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.+ Please refer the below code to reproduce the issue. {code:java} // code placeholder import org.apache.hadoop.mapred.JobConf val hadoopConf = new JobConf() 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() {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
