英文:
Apache Spark spark-submit k8s API https ERROR
问题
Spark版本：2.4.4
k8s版本：1.18
我有一个Spark集群和一个k8s集群。
我按照Spark文档：https://spark.apache.org/docs/2.4.4/running-on-kubernetes.html 进行操作。
当我在k8s上使用HTTP代理提交作业时：一切正常。
但是，使用k8s上的本机HTTPS API时，我收到以下错误：
之前我不得不将k8s API证书导入到我的主Spark中（keytool）。
internal.WatchConnectionManager: 执行失败：HTTP 403，状态：403 - 禁止“spark-pi-1598541432880-driver”：用户“system:anonymous”无法在命名空间“default”中观察资源“pods”。java.net.ProtocolException: 预期的HTTP 101响应，但是实际是'403 Forbidden'at okhttp3.internal.ws.RealWebSocket.checkResponse(RealWebSocket.java:216)at okhttp3.internal.ws.RealWebSocket$2.onResponse(RealWebSocket.java:183)at okhttp3.RealCall$AsyncCall.execute(RealCall.java:141)at okhttp3.internal.NamedRunnable.run(NamedRunnable.java:32)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149)at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)at java.lang.Thread.run(Thread.java:748)
这很奇怪，因为没有匿名用户。
我已经尝试将“anonymous”用户添加到k8s，但没有效果。
如果我尝试不导入API证书，则会收到以下错误：
Caused by: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException：PKIX路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到到请求目标的有效认证路径at sun.security.ssl.Alerts.getSSLException(Alerts.java:198)at sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1967)at sun.security.ssl.Handshaker.fatalSE(Handshaker.java:331)at sun.security.ssl.Handshaker.fatalSE(Handshaker.java:325)at sun.security.ssl.ClientHandshaker.serverCertificate(ClientHandshaker.java:1688)
我提交作业的命令：
-bash-4.2$ spark-submit --master k8s://https://ip:port --deploy-mode cluster --name spark-pi --class org.apache.spark.examples.SparkPi --conf spark.executor.instances=3 --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark --conf spark.kubernetes.container.image=docker.io/spawnxx/spark:fink-test-2 hdfs://hdfs_ip/user/sacha.pateyron/spark-examples_2.11-2.4.4.jar 1000
Apache Spark本地不支持k8s的https API（因此我必须导入证书）？
有什么想法吗？
英文:
Spark version :2.4.4
k8s version : 1.18
I have a Spark and a k8s cluster.
I followed Spark documentation : https://spark.apache.org/docs/2.4.4/running-on-kubernetes.html
When I submit a job with an HTTP proxy on k8s : everything is ok.
However with the native HTTPS API on k8s I got this error :
Previously I had to import k8s API cert to my master Spark (keytool).
internal.WatchConnectionManager: Exec Failure: HTTP 403, Status: 403 - pods "spark-pi-1598541432880-driver" is forbidden: User "system:anonymous" cannot watch resource "pods" in API group "" in the namespace "default"java.net.ProtocolException: Expected HTTP 101 response but was '403 Forbidden'at okhttp3.internal.ws.RealWebSocket.checkResponse(RealWebSocket.java:216)at okhttp3.internal.ws.RealWebSocket$2.onResponse(RealWebSocket.java:183)at okhttp3.RealCall$AsyncCall.execute(RealCall.java:141)at okhttp3.internal.NamedRunnable.run(NamedRunnable.java:32)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149)at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)at java.lang.Thread.run(Thread.java:748)
This is curious because there is no user anonymous.
I already try to add an 'anonymous' user to k8s but it has no effect.
If I try without import the API cert I got this error :
Caused by: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested targetat sun.security.ssl.Alerts.getSSLException(Alerts.java:198)at sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1967)at sun.security.ssl.Handshaker.fatalSE(Handshaker.java:331)at sun.security.ssl.Handshaker.fatalSE(Handshaker.java:325)at sun.security.ssl.ClientHandshaker.serverCertificate(ClientHandshaker.java:1688)
My command to submit my job :
-bash-4.2$ spark-submit --master k8s://https://ip:port --deploy-mode cluster --name spark-pi --class org.apache.spark.examples.SparkPi --conf spark.executor.instances=3 --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark --conf spark.kubernetes.container.image=docker.io/spawnxx/spark:fink-test-2 hdfs://hdfs_ip/user/sacha.pateyron/spark-examples_2.11-2.4.4.jar 1000
K8s https API is not supported natively by Apache Spark (so I must import the cert) ?
Any idea ?

Solution:
HTTPS k8s API使用证书和令牌进行身份验证。
首先下载k8s HTTPS API：
在主节点spark上 -
echo -n|openssl s_client -connect ip_master_k8s:port_https_api|openssl x509 -outform PEM > selfsigned_certificate.pem
在k8s主节点机器上获取spark令牌：
kubectl get secretkubectl describe secret spark-token-XXX
然后在Spark主节点上使用证书和令牌提交作业：
spark-submit --master k8s://https://ip_master_k8s:port_https_api --deploy-mode cluster --name spark-pi --class org.apache.spark.examples.SparkPi --conf spark.executor.instances=3 --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark --conf spark.kubernetes.container.image=your_image --conf spark.kubernetes.authenticate.submission.caCertFile=selfsigned_certificate.pem --conf spark.kubernetes.authenticate.submission.oauthToken=spark-token-XXX hdfs://ip_master_hdfs/my_jar
英文:
Solution :
HTTPS k8s API use cert and token for authentication.
First download k8s HTTPS API :
On master spark ->
echo -n|openssl s_client -connect ip_master_k8s:port_https_api|openssl x509 -outform PEM > selfsigned_certificate.pem
On k8s master machine get spark token :
kubectl get secretkubectl describe secret spark-token-XXX
Then on Spark master we submit a job with cert and token :
spark-submit --master k8s://https://ip_master_k8s:port_https_api --deploy-mode cluster --name spark-pi --class org.apache.spark.examples.SparkPi --conf spark.executor.instances=3 --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark --conf spark.kubernetes.container.image=your_image --conf spark.kubernetes.authenticate.submission.caCertFile=selfsigned_certificate.pem --conf spark.kubernetes.authenticate.submission.oauthToken=spark-token-XXX hdfs://ip_master_hdfs/my_jar
