从 PySpark 推送数据以保护 ElasticSearch - 证书问题

Question

我有一个启用了 SearchGuard 的 ElasticSearch 集群。我正在尝试使用 Spark 将数据推送到 ElasticSearch 中。

操作系统 - CentOS7 ElasticSearch 版本 - 6.4.1 Spark - 2.3.0 Java - openjdk-1.8.0 Yarn - 2.7.3 HDFS - 2.7.3 HDP - 2.6.5.0

ElasticSearch 已通过 PEM 密钥使用 SearchGuard 进行保护。chain-ca.pem 已添加到所有 Spark 节点上的信任库中。我已在 PySpark 代码中添加了所需的配置。

es_write_conf = {
    "es.nodes" : "esm1,esm2,esm3",
    "es.port" : "9200",
    "es.resource" : str(topic+"_"+year_week+"/"+topic),
    "es.input.json": "true",
    "es.nodes.ingest.only": "true",
    "es.net.http.auth.user": "admin",
    "es.net.http.auth.pass": "admin",
    "es.net.ssl":"true",
    "es.net.ssl.cert.allow.self.signed":"true",
    "es.net.ssl.keystore.location":"file:///usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64/jre/lib/security/cacerts",
    "es.net.ssl.keystore.pass":"changeit"
}

我在 hdfs 用户上使用 Spark-submit 运行此命令：

spark-submit --master local[4] --jars /home/hdfs/jars/elasticsearch-hadoop-6.4.1.jar,/home/hdfs/jars/spark-streaming-kafka-0-8-assembly_2.11-2.3.1.jar /home/hdfs/code/ingestion.py demo_machine001

产生了这个错误。

Caused by: org.elasticsearch.hadoop.rest.EsHadoopTransportException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

通过使用 sudo 运行 Spark 提交解决了这个问题。我之前更改了 cacerts 文件的权限和所有权，但它产生了相同的错误。

我试图通过 YARN 运行它并得到相同的错误。

通过以下方式运行它：

spark-submit --master yarn --deploy-mode cluster --jars /home/hdfs/jars/elasticsearch-hadoop-6.4.1.jar,/home/hdfs/jars/spark-streaming-kafka-0-8-assembly_2.11-2.3.1.jar /home/hdfs/code/ingestion.py demo_machine001

产生错误：

Caused by: org.elasticsearch.hadoop.rest.EsHadoopTransportException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

通过以下方式运行它：

sudo SPARK_HOME=/usr/hdp/current/spark2-client SPARK_MAJOR_VERSION=2 PYTHONPATH=$SPARK_HOME/python/:$PYTHONPATH PYTHONPATH=$SPARK_HOME/python/lib/py4j-0.10.6-src.zip:$PYTHONPATH spark-submit --master yarn --deploy-mode cluster --jars /home/hdfs/jars/elasticsearch-hadoop-6.4.1.jar,/home/hdfs/jars/spark-streaming-kafka-0-8-assembly_2.11-2.3.1.jar /home/hdfs/everlytics/ingestion.py demo_machine001

产生错误：

Caused by: org.elasticsearch.hadoop.rest.EsHadoopTransportException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

我已将 cacerts 文件放入 hdfs 并在 Spark 代码中进行了更改：

"es.net.ssl.keystore.location":"hdfs://spm1:8020/certificates/cacerts"

这产生了一个错误：

Caused by: org.elasticsearch.hadoop.EsHadoopIllegalStateException: Cannot initialize SSL - Expected to find keystore file at [hdfs://spm1:8020/certificates/cacerts] but was unable to. Make sure that it is available on the classpath, or if not, that you have specified a valid URI.

我对 hdfs 和本地文件系统上的 cacerts 的权限和所有权进行了多次迭代，但无济于事。

我还将 cacerts 复制到每个节点上的 /tmp 以进行全局访问，但到目前为止没有任何效果。
