Spark 抱怨 AWS EMR 中缺少 java.library.path

Question

我们有一个 AWS EMR 集群，我们在其中运行一些 spark 作业。作业是从 EC2 实例的 docker 容器提交的。所有容器运行ning spark 作业投诉低于错误。我试过在 spark-env 和 yarn-env 中添加 LD_LIBRARY_PATH，但错误仍然出现。由于这个问题，我们无法读取任何 CSV。

你们谁能帮忙吗？

添加后得到这个工作：

LD_LIBRARY_PATH=/usr/lib/hadoop-lzo/lib/*:/usr/lib/hadoop/lib/native:/usr/lib/hadoop-lzo/lib/native:/docker/usr/lib/hadoop/lib/native:/docker/usr/lib/hadoop-lzo/lib/native

LD_PRELOAD=/lib64/librt.so.1

    new SparkConf().setExecutorEnv("LD_LIBRARY_PATH", LD_LIBRARY_PATH)
                   .setExecutorEnv("LD_PRELOAD", LD_PRELOAD)

从 core-site 中删除属性以下。xml:

<property>
    <name>io.compression.codec.lzo.class</name>
    <value>com.hadoop.compression.lzo.LzoCodec</value>
  </property>
