Problem Description

Spark-submit uses kryo serialization parameters when submitting a task. The program reports an error about the size of the serialization buffer during the calculation process. The task submission code:

spark-submit \
    --class cn.yd.spark.logAnalyze.LogAnalyze \
    --name 'log_analyze' \
    --queue offline \
    --master yarn \
    --deploy-mode cluster \
    --conf spark.sql.shuffle.partitions=500 \
    --conf spark.default.parallelism=500 \
    --conf spark.sql.parquet.compression.codec=snappy \
    --conf spark.kryoserializer.buffer.max=128m \
    --conf spark.serializer=org.apache.spark.serializer.KryoSerializer \
    --conf spark.locality.wait.node=6 \
    --num-executors 4 \
    --executor-cores 1 \
    --driver-memory 5g \
    --executor-memory 2g \
    --conf 'spark.driver.extraJavaOptions= -XX:+UseCodeCacheFlushing -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:+ParallelRefProcEnabled  -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/data/log/offline/store_sort_week_driver_error.dump' \
    --conf 'spark.executor.extraJavaOptions=-XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:+ParallelRefProcEnabled  -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/data/log/offline/store_sort_week_executor_error.dump' \
    /data/xxx.jar

problem causes

This problem is due to the spark.kryoserializer.buffer.max=128mset through the parameter value results in small, since the time required to write data to check on the sequence of parameters, if the maximum value of the data to be written is greater than the set will be thrown
Source :

// Check the constructor method, where the maximum value of the buffer will be set
/** Creates a new Output for writing to a byte array.
 * @param bufferSize The initial size of the buffer.
 * @param maxBufferSize The buffer is doubled as needed until it exceeds maxBufferSize and an exception is thrown. Can be -1
 *           for no maximum. */
public Output (int bufferSize, int maxBufferSize) {
	if (maxBufferSize < -1) throw new IllegalArgumentException("maxBufferSize cannot be < -1: " + maxBufferSize);
	this.capacity = bufferSize;
	this.maxCapacity = maxBufferSize == -1 ? Integer.MAX_VALUE : maxBufferSize;
	buffer = new byte[bufferSize];
}


// From here it can be seen that the exception is thrown when capacity == maxCapacity
/** @return true if the buffer has been resized. */
	protected boolean require (int required) throws KryoException {
		if (capacity - position >= required) return false;
		if (required > maxCapacity)
			throw new KryoException("Buffer overflow. Max capacity: " + maxCapacity + ", required: " + required);
	flush();
	while (capacity - position < required) {
		if (capacity == maxCapacity)
		throw new KryoException("Buffer overflow. Available: " + (capacity - position) + ", required: " + required);
		// Grow buffer.
		if (capacity == 0) capacity = 1;
		capacity = Math.min(capacity * 2, maxCapacity);
		if (capacity < 0) capacity = maxCapacity;
		byte[] newBuffer = new byte[capacity];
		System.arraycopy(buffer, 0, newBuffer, 0, position);
		buffer = newBuffer;
	}
	return true;
}

solution

Adjust the maximum value of sequence serialization parameters, such as 1G
Serialization method is not applicable, two parameters are removed from the submission script
