我正在尝试从spark应用程序连接到hive metastore,但每次它在尝试连接时被卡住,并因超时而崩溃:
INFO metastore:376 - Trying to connect to metastore with URI thrift://hive-metastore:9083
WARN metastore:444 - set_ugi() not successful, Likely cause: new client talking to old server. Continuing without it.
org.apache.thrift.transport.TTransportException: java.net.SocketTimeoutException: Read timed out
应用程序在我创建外部配置单元表的那一行崩溃
我在kubernetes集群中运行hivemetastore和spark应用程序(使用spark8s操作符)。我使用telnet(node-ip:service-node-port)检查了集群外部的hive metastore服务的可访问性,并将该服务 curl 到集群内部,该服务似乎是可评估的。这个错误的原因是什么?
这是spark应用程序中配置单元元存储uri的配置
val sparkSession = SparkSession
.builder()
.config(sparkConf)
.config("hive.metastore.uris", "thrift://hive-metastore:9083")
.config("hive.exec.dynamic.partition", "true")
.config("hive.exec.dynamic.partition.mode", "nonstrict")
.enableHiveSupport()
.getOrCreate()
配置单元metastore yaml配置如下所示:
apiVersion: v1
kind: Service
metadata:
name: hive-metastore-np
spec:
selector:
app: hive-metastore
ports:
- protocol: TCP
targetPort: 9083

更新:当我试图 curl Hive-metastore:9083,该服务是可访问的,但它返回一个空响应,这意味着配置单元元存储区k8s定义可能有问题

当集群中的配置单元jar的版本与spark使用的配置单元jar的版本不一致(通常与您使用的spark版本一致)时,就会发生此错误。您需要确定集群中使用的配置单元jar的版本,并将这些jar添加到spark映像中。然后,通过向sparksession添加以下配置,可以使sparksession使用这些兼容的配置单元jar:
