python-3.x - 无法从 pyspark 数据框保存到 ES

问题描述

我正在使用 Jupyter 笔记本。我有一个使用以下命令加载的 pyspark 数据框

os.environ['PYSPARK_SUBMIT_ARGS'] = '--jars /home/hdfs/elasticsearch-spark-20_2.11-6.1.2.jar pyspark-shell'

conf = SparkConf(). \
    setAppName('app-name'). \
    setMaster('yarn')

spark = SparkSession.builder. \
    appName("app-name"). \
    config(conf=conf). \
    getOrCreate()

df = spark.read.option('delimiter', '|').csv("hdfs://"+ filename )

然后我需要通过以下命令将此 Dataframe 保存到 ElasticSearch 中：

df.write.format("org.elasicsearch.spark.sql") \
    .mode('append') \
    .option("es.resource", flame_index+ "/cdr") \
    .option("es.nodes", "10.10.10.10:9200") \
    .option("es.net.ssl", "true") \
    .option("es.net.ssl.cert.allow.self.signed", "false") \
    .option("es.net.http.auth.user", "xxxxx") \
    .option("es.net.http.auth.pass", "xxxxxx" ) \
    .option("es.net.ssl.truststore.location", "file:///tmp/xxxxx.jks") \
    .option("es.net.ssl.truststore.pass", "xxxxxx") \
    .option("es.net.ssl.keystore.location", "file:///tmp/xxxxx.jks") \
    .option("es.net.ssl.keystore.pass", "xxxxxx") \
    .option("es.net.ssl.protocol","TLS") \
    .save()

但是下面的命令给了我下面的错误：

---------------------------------------------------------------------------

该代码在 hadoop 集群上运行。ElasticSearch 也在集群中。

我检查了文件 /home/hdfs/elasticsearch-spark-20_2.11-6.1.2.jar 存在

任何人都可以帮助我为什么遇到上述错误以及如何解决它？
