无法从pyspark读取密钥库文件

问题描述 投票：9回答：3

我正在使用下面的代码段将Hive连接并加载数据到Elasticsearch（v 6.2），没有任何问题

ADD JAR file:///<>/elasticsearch-hadoop-hive-6.2.2.jar;
ADD FILE file:///<>/mycerts.jks;

CREATE EXTERNAL TABLE if not exists my_db.my_es_table
(
col1 int,
col2 string,
col3 string,
col4 timestamp,
key_id string
)
COMMENT 'data into ES'
STORED BY 'org.elasticsearch.hadoop.hive.EsStorageHandler'
TBLPROPERTIES('es.resource' = 'index1/type1',
'es.index.auto.create'='true',
'es.nodes'='<vip_name>',
'es.port'='9200',
'es.net.http.auth.user'='<user>',
'es.net.http.auth.pass'='pwd',
'es.net.ssl.protocol'='SSL',
'es.net.ssl'='TRUE',
'es.net.ssl.truststore.location'='mycerts.jks',
'es.net.ssl.truststore.pass'='<pwd>',
'es.mapping.id'='key_id'
);

INSERT OVERWRITE TABLE my_db.my_es_table
SELECT
col1,
col2,
col3,
col4,
key_id
FROM my_db.stagging_data;

但是，当试图将同一块迁移到py-spark时，会抛出异常

   org.elasticsearch.hadoop.EsHadoopIllegalArgumentException: Expected to find keystore file at [file:///<path>/mycerts.jks] but was unable to. Make sure that it is available on the classpath, or if not, that you have specified a valid URI

下面是我尝试获取火花的代码片段

df_delta=sqlContext.table('my_db.stagging_data')
status=df_delta.rdd.map(lambda row:(None,row.asDict())).saveAsNewAPIHadoopFile(path='-', outputFormatClass="org.elasticsearch.hadoop.mr.EsOutputFormat",keyClass="org.apache.hadoop.io.NullWritable",valueClass="org.elasticsearch.hadoop.mr.LinkedMapWritable",conf={'es.resource' : 'index1/type1','es.index.auto.create':'true','es.nodes':'<vip_name>','es.port':'9200','es.net.http.auth.user':'<user>','es.net.http.auth.pass':'<pwd>','es.net.ssl':'true','es.net.ssl.truststore.location':'file:///<path>/mycerts.jks','es.net.ssl.truststore.pass':'<pwd>','es.mapping.id' : 'key_id'})

我正在使用以下命令调用shell-

pyspark --jars <path>/elasticsearch-spark-20_2.11-6.2.2.jar --py-files <path>/mycerts.jks

下面我要添加整个日志

连接到py-spark后，我可以读取和打印jks文件。无法解决此问题。有人可以建议。

python apache-spark elasticsearch pyspark jks

我认为您使用的是错误的选项

对于Python，您可以使用spark-submit的--py-files参数添加。py，.zip或.egg文件，以与您的应用程序一起分发]

相反，您想要--files

--files FILES: Comma-separated list of files to be placed in the working directory of each executor. File paths of these files in executors can be accessed via SparkFiles.get(fileName)

将其放置在执行程序中的其他路径上，然后可以使用#分隔符

spark-submit ... --files mycerts.jks#/<path>/mycerts.jks

在代码内，您可以从SparkFiles.get("mycerts.jks")获取对路径的引用，该路径将返回文件的绝对路径

正如上面的cricket_007所指出的，您使用的选项--py-files不正确。而是使用--files选项上传您的证书文件。

此外，这些文件不是上传到这些执行程序的本地文件系统中，而是上传到HDFS。因此，您在Spark代码中为证书文件传递的路径也不正确，因为它指向本地文件系统。

'es.net.ssl.truststore.location':'file:///<path>/mycerts.jks'

您可以在spark Submit命令中使用带文件的＃分隔符选项将文件上传到HDFS上指定的文件上>]

spark-submit ... --files mycerts.jks#/<path>/mycerts.jks

然后在火花代码中使用相同的路径来访问文件。
'es.net.ssl.truststore.location':'/<path>/mycerts.jks'

根据您的堆栈消息，看来您的<path显然是错误的。您在--jars和--py-files之后的path
