ssl - GCP Dataproc - 无法构造 kafka 消费者，无法加载 JKS 类型的 SSL keystore dataproc.jks

Question

我正在尝试在 GCP Dataproc 上运行结构化流程序，该程序从 Kafka 访问数据并打印它。
访问 Kafka 使用 SSL，并且信任库和 keystore 文件存储在存储桶中。
我正在使用 Google Storage API 访问存储桶，并将文件存储在当前工作目录中。信任库和 keystore 被传递给 Kafka 消费者/生产者。
但是 - 我遇到了一个错误
命令 :

gcloud dataproc jobs submit pyspark /Users/karanalang/Documents/Technology/gcp/DataProc/StructuredStreaming_Kafka_GCP-Batch-feb2-v2.py  --cluster dataproc-ss-poc  --properties spark.jars.packages=org.apache.spark:spark-sql-kafka-0-10_2.12:3.2.0 --region us-central1

代码如下所示:

spark = SparkSession.builder.appName('StructuredStreaming_VersaSase').getOrCreate()

kafkaBrokers='<broker-ip>:9094'
topic = "versa-sase"
security_protocol="SSL"

# Google Storage API to access the keys in the buckets
client = storage.Client()
bucket = client.get_bucket('ssl-certs-karan')

blob_ssl_truststore = bucket.get_blob('cap12.jks')
ssl_truststore_location = '{}/{}'.format(os.getcwd(), blob_ssl_truststore.name) 
blob_ssl_truststore.download_to_filename(ssl_truststore_location)

ssl_truststore_password="<ssl_truststore_password>"

blob_ssl_keystore = bucket.get_blob('dataproc-versa-sase-p12-1.jks')
ssl_keystore_location = '{}/{}'.format(os.getcwd(), blob_ssl_keystore.name) 
blob_ssl_keystore.download_to_filename(ssl_keystore_location)


ssl_keystore_password="<ssl_keystore_password>"
consumerGroupId = "versa-sase-grp"
checkpoint = "gs://ss-checkpoint/"

print(" SPARK.SPARKCONTEXT -> ", spark.sparkContext)


df = spark.read.format('kafka')\
    .option("kafka.bootstrap.servers",kafkaBrokers)\
    .option("kafka.security.protocol","SSL") \
    .option("kafka.ssl.truststore.location",ssl_truststore_location) \
    .option("kafka.ssl.truststore.password",ssl_truststore_password) \
    .option("kafka.ssl.keystore.location", ssl_keystore_location)\
    .option("kafka.ssl.keystore.password", ssl_keystore_password)\
    .option("subscribe", topic) \
    .option("kafka.group.id", consumerGroupId)\
    .option("startingOffsets", "earliest") \
    .load()

   print(" df -> ", df)
   query = df.selectExpr("CAST(value AS STRING)", "CAST(key AS STRING)", "topic", "timestamp") \
    .write \
    .format("console") \
    .option("numRows",100)\
    .option("checkpointLocation", checkpoint) \
    .option("outputMode", "complete")\
    .option("truncate", "false") \
    .save("output")

错误 :

在我的 Mac 上，我使用 PKCS 文件 (.p12) 并且能够以 SSL 模式访问 Kafka 集群。但是，在 Dataproc 中 - 似乎预期的文件格式是 JKS。
这是我用来将 .p12 文件转换为 JKS 格式的命令:

keytool -importkeystore -srckeystore dataproc-versa-sase.p12 -srcstoretype pkcs12 -srcalias versa-sase-user -destkeystore dataproc-versa-sase-p12-1.jks -deststoretype jks -deststorepass <password> -destalias versa-sase-user

需要做什么来解决这个问题？
Spark 程序似乎无法访问 JKS 文件？
蒂亚!

Answer 1

如果您想使用 jks，我会添加以下选项

.option("kafka.ssl.keystore.type", "JKS")
.option("kafka.ssl.truststore.type", "JKS")

顺便说一下，这也适用于PKCS12

.option("kafka.ssl.keystore.type", "PKCS12")
.option("kafka.ssl.truststore.type", "PKCS12")

就像前面提到的那样，您可以检查是否是 jdk 兼容性问题，如下所示:

keytool -v -list -storetype pkcs12 -keystore kafka-client-jdk8-truststore.p12

如果您收到一条显示 keystore 的消息，则说明您是明确的，但如果您收到一条消息说找不到标识符，则表示 jdks 存在差异。
