From f9d20b9a553509b80e7bdeb38a725e8a20bcce06 Mon Sep 17 00:00:00 2001 From: Fei Wang Date: Tue, 8 Dec 2015 21:32:31 -0800 Subject: [PATCH] [SPARK-12222] [CORE] Deserialize RoaringBitmap using Kryo serializer throw Buffer underflow exception Jira: https://issues.apache.org/jira/browse/SPARK-12222 Deserialize RoaringBitmap using Kryo serializer throw Buffer underflow exception: ``` com.esotericsoftware.kryo.KryoException: Buffer underflow. at com.esotericsoftware.kryo.io.Input.require(Input.java:156) at com.esotericsoftware.kryo.io.Input.skip(Input.java:131) at com.esotericsoftware.kryo.io.Input.skip(Input.java:264) ``` This is caused by a bug of kryo's `Input.skip(long count)`(https://github.com/EsotericSoftware/kryo/issues/119) and we call this method in `KryoInputDataInputBridge`. Instead of upgrade kryo's version, this pr bypass the kryo's `Input.skip(long count)` by directly call another `skip` method in kryo's Input.java(https://github.com/EsotericSoftware/kryo/blob/kryo-2.21/src/com/esotericsoftware/kryo/io/Input.java#L124), i.e. write the bug-fixed version of `Input.skip(long count)` in KryoInputDataInputBridge's `skipBytes` method. more detail link to https://github.com/apache/spark/pull/9748#issuecomment-162860246 Author: Fei Wang Closes #10213 from scwf/patch-1. --- .../spark/serializer/KryoSerializer.scala | 10 ++++++- .../serializer/KryoSerializerSuite.scala | 28 ++++++++++++++++++- 2 files changed, 36 insertions(+), 2 deletions(-) diff --git a/core/src/main/scala/org/apache/spark/serializer/KryoSerializer.scala b/core/src/main/scala/org/apache/spark/serializer/KryoSerializer.scala index faa00f2e33461..7c731f637330f 100644 --- a/core/src/main/scala/org/apache/spark/serializer/KryoSerializer.scala +++ b/core/src/main/scala/org/apache/spark/serializer/KryoSerializer.scala @@ -368,7 +368,15 @@ private[serializer] class KryoInputDataInputBridge(input : KryoInput) extends Da override def readUTF(): String = input.readString() // readString in kryo does utf8 override def readInt(): Int = input.readInt() override def readUnsignedShort(): Int = input.readShortUnsigned() - override def skipBytes(n: Int): Int = input.skip(n.toLong).toInt + override def skipBytes(n: Int): Int = { + var remaining: Long = n + while (remaining > 0) { + val skip = Math.min(Integer.MAX_VALUE, remaining).asInstanceOf[Int] + input.skip(skip) + remaining -= skip + } + n + } override def readFully(b: Array[Byte]): Unit = input.read(b) override def readFully(b: Array[Byte], off: Int, len: Int): Unit = input.read(b, off, len) override def readLine(): String = throw new UnsupportedOperationException("readLine") diff --git a/core/src/test/scala/org/apache/spark/serializer/KryoSerializerSuite.scala b/core/src/test/scala/org/apache/spark/serializer/KryoSerializerSuite.scala index 23a1fdb0f5009..21490d1e2dcdd 100644 --- a/core/src/test/scala/org/apache/spark/serializer/KryoSerializerSuite.scala +++ b/core/src/test/scala/org/apache/spark/serializer/KryoSerializerSuite.scala @@ -17,16 +17,20 @@ package org.apache.spark.serializer -import java.io.{ByteArrayInputStream, ByteArrayOutputStream} +import java.io.{ByteArrayInputStream, ByteArrayOutputStream, FileOutputStream, FileInputStream} import scala.collection.mutable import scala.reflect.ClassTag import com.esotericsoftware.kryo.Kryo +import com.esotericsoftware.kryo.io.{Input => KryoInput, Output => KryoOutput} + +import org.roaringbitmap.RoaringBitmap import org.apache.spark.{SharedSparkContext, SparkConf, SparkFunSuite} import org.apache.spark.scheduler.HighlyCompressedMapStatus import org.apache.spark.serializer.KryoTest._ +import org.apache.spark.util.Utils import org.apache.spark.storage.BlockManagerId class KryoSerializerSuite extends SparkFunSuite with SharedSparkContext { @@ -319,6 +323,28 @@ class KryoSerializerSuite extends SparkFunSuite with SharedSparkContext { assert(thrown.getMessage.contains(kryoBufferMaxProperty)) } + test("SPARK-12222: deserialize RoaringBitmap throw Buffer underflow exception") { + val dir = Utils.createTempDir() + val tmpfile = dir.toString + "/RoaringBitmap" + val outStream = new FileOutputStream(tmpfile) + val output = new KryoOutput(outStream) + val bitmap = new RoaringBitmap + bitmap.add(1) + bitmap.add(3) + bitmap.add(5) + bitmap.serialize(new KryoOutputDataOutputBridge(output)) + output.flush() + output.close() + + val inStream = new FileInputStream(tmpfile) + val input = new KryoInput(inStream) + val ret = new RoaringBitmap + ret.deserialize(new KryoInputDataInputBridge(input)) + input.close() + assert(ret == bitmap) + Utils.deleteRecursively(dir) + } + test("getAutoReset") { val ser = new KryoSerializer(new SparkConf).newInstance().asInstanceOf[KryoSerializerInstance] assert(ser.getAutoReset)
