spark 执行报错 java.io.EOFException: Premature EOF from inputStream

使用spark2.4跟spark2.3 做替代公司现有的hive选项。

跑个别任务spark有以下错误

排查原因 发现是读取0 size 大小的文件时出错

并没有发现spark官方有修复该bug

手动修改代码 过滤掉这种文件

在 HadoopRDD.scala 类相应位置修改如图即可

      // We get our input bytes from thread-local Hadoop FileSystem statistics.
      // If we do a coalesce, however, we are likely to compute multiple partitions in the same
      // task and in the same thread, in which case we need to avoid override values written by
      // previous partitions (SPARK-13071).

        getBytesReadCallback.foreach { getBytesRead =>
          inputMetrics.setBytesRead(existingBytesRead + getBytesRead())
