來自Spark Scala的Hbase Kerberos連接

Question

我正在嘗試從spark scala外殼連接到以kerberized保護的Hbase集群，下面是我的代碼，感謝您提供有關錯誤的幫助。 我正在使用以下文件在Spark Shell中傳遞hdfs-site.xml，hbase-site.xml，core-site.xml和我的keytab

import org.apache.hadoop.conf.Configuration 
import org.apache.hadoop.hbase.HBaseConfiguration
import org.apache.hadoop.hbase.client.Connection
import org.apache.hadoop.hbase.client.ConnectionFactory 
import org.apache.hadoop.hbase.TableName
import org.apache.hadoop.security.UserGroupInformation

val conf: Configuration = HBaseConfiguration.create()
conf.set("hbase.zookeeper.quorum", "xxxxx1@abc.com,xxxxx2@abc.com,xxxxx3@abc.com")
conf.set("zookeeper.znode.parent", "/hbase-secure") 
conf.setInt("hbase.client.scanner.caching", 10000)
conf.set("hbase.rpc.controllerfactory.class","org.apache.hadoop.hbase.ipc.RpcControllerFactory")
conf.set("hbase.rpc.controllerfactory.class","org.apache.hadoop.hbase.ipc.RpcControllerFactory")
conf.set("hadoop.security.authentication", "kerberos")
conf.set("hbase.security.authentication", "kerberos")
val userGroupInformation = UserGroupInformation.loginUserFromKeytabAndReturnUGI("XXX@abc.COM", "/u/xxxxx/XXXX.keytab")
UserGroupInformation.setLoginUser(userGroupInformation)
val connection: Connection = ConnectionFactory.createConnection(conf)
print(connection)
val admin = connection.getAdmin
val listtables = admin.listNamespaceDescriptors()
]

I see a lot of warning in the process as below 
warning: Class

找不到org.apache.hadoop.hbase.classification.InterfaceAudience-繼續存根。

Answer 1

您的Zookeeper配置缺少Zookeeper端口。 加，

conf.set("hbase.zookeeper.property.clientPort", "2181")

我想建議您一些其他的事情，

1. 之后，您可能會遇到火花配置問題。 復制hdfs-site.xml，hbase-site.xml，core-site.xml和yarn-site.xml（如果使用的是yarn）以生成conf文件夾。

2. 向hbase配置對象添加資源

    conf.addResource("/path/to/hbase-site.xml"); 

3. 設置Java屬性

    //Point to the krb5.conf file. Enable Kerberos debug. System.setProperty("java.security.krb5.conf", "/etc/krb5.conf"); System.setProperty("sun.security.krb5.debug", "true"); 

希望這會有所幫助...
