我正在尝试在Apache Kudu上运行我的代码。虽然在我的本地kudu设置上运行正常，但我在同一台计算机上拥有主服务器和平板电脑服务器。现在，通过在Cloudera Hadoop env上通过rpm软件包安装手动安装Kudu，我得到了例外。
我正在尝试通过spark加载一个csv文件并坚持到Kudu。我已经在工作状态下设置了以下内容：
在不同的节点上安装了Kudu主机和平板电脑（它们正在运行） 在所有群集节点上都设置了新用户（kudu）的kereberos票证。 （但是，只有一台母版和一台平板电脑，只需对其中两个进行初始化即可）。针对每个组件（例如spark，hive等）都制定了护林员政策，以便向另一个组件/从另一个组件提交作业
/**
* Storing the dataframe into Kudu
*
* @param df the dataframe to store.
*/
def store(df: DataFrame): Unit = {
// Init configuration.
log.info("kuduMaster: " + config.kuduMaster)
val kuduContext = new KuduContext(config.kuduMaster, config.sparkSession.sparkContext)
val primaryKeys = SchemaMapper.primaryKeys(config.tableName).get
// Create Table if non existing
if (!kuduContext.tableExists(config.tableName)) {
log.info("Create Table, tableName: " + config.tableName)
kuduContext.createTable(
config.tableName, df.schema, primaryKeys, new CreateTableOptions()
.setNumReplicas(config.kuduNumReplicas)
.addHashPartitions(primaryKeys.asJava, config.kuduBuckets))
}
Spark插入Kudu时出现异常。成功启动Kerberos主体后： 以下是每次出现的例外情况。我试图从kudu安装所在的Hadoop的同一节点上并通过kudu用户运行它，但是它不起作用。
