【问题描述】：
我正在运行一个 Spark 流应用程序，其中每个批次使用 SqlContext 将其最终输出以 parquet 格式写入 S3。
我能够让这个应用程序在 EMR 中成功运行。
但是，在运行几个小时后，spark 作业突然停止在 FileNotFoundException。
我不确定接下来该做什么。
有关如何调试/修复此问题的任何指示都会很有用。
我的应用程序使用 Spark 2.2.1、EMR 5.1.1 和 Java 8。
我的流媒体应用程序代码
public class StreamingApp {
JavaStreamingContext initDAG() {
JavaSparkContext sc = new JavaSparkContext(sparkConf);
// new context
JavaStreamingContext jssc = new JavaStreamingContext(sc, batchInterval);
SQLContext sqlContext = new SQLContext(sc);
...
// Converting to Dataset's Row type
JavaDStream<Row> rowStream = inputStream.map(new ObjectToRowMapperFunction());
// Writing to Disk
rowStream.foreachRDD(new RddToParquetFunction(sqlContext));
return jssc;
}
...
}
public class RddToParquetFunction implements VoidFunction<JavaRDD<Row>> {
private final StructType userStructType;
private final SQLContext sqlContext;
public RddToParquetFunction(SQLContext sqlContext) {
userStructType = ProtobufSparkStructMapper.schemaFor(UserMessage.class);
this.sqlContext = sqlContext;
}
@Override
public void call(JavaRDD<Row> rowRDD) throws Exception {
Dataset<Row> userDataFrame = sqlContext.createDataFrame(rowRDD, userStructType);
userDataFrame.write().mode(SaveMode.Append).parquet("s3://XXXXXXX/XXXXX/");
}
}
