记一次生产环境Hbase填坑之路、Hbase客户端登陆、kerberos认证、端口列表、Pod上手撕代码【Hbase最佳实践】

web 2025/8/25 20:00:24

背景

1、软件系统（转储系统）需要向生产环境迁移：迁到国产操作系统、国产资源池（Hbase存储不变）

2、老环境上的转储系统本身存在写入hbase的性能问题、及部分省份写入hbase失败的问题（20%失败）

3、全国31个省写入数据量大

4、向国产环境迁移没有成功，该工程（6年前的工程）作者之前从来没有参与过

5、新的环境迁移涉及主机端口开通、及网络端口打通等诸多事项

环境

 1、Oracle JDK8u202(Oracle JDK8最后一个非商业版本)   下载地址：Oracle JDK8u202

 2、Hbase 1.1.2.2.5  Apache HBase – Apache HBase Downloads（多年前的项目，所以其版本较旧， 该版本已归档：   Index of /dist/hbase ）

 3、Hadoop 2.7.1.2.5  Apache Hadoop （该版本已归档： Central Repository: org/apache/hadoop/hadoop-common/2.7.1）

 4、Kerberos 1.10.3-10   MIT Kerberos Consortium  （该版本已归档：Historic MIT Kerberos Releases）

Hbase测试代码

话不多说，先看代码作者在POD上手撕的测试代码，这是指登陆代码（因为只要登陆成功就能解决所有问题）：

主类

package com.asiainfo.crm.ai;import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.security.UserProvider;
import org.apache.hadoop.hbase.shaded.com.google.common.base.Preconditions;
import org.apache.hadoop.hbase.util.Strings;
import org.apache.hadoop.net.DNS;/***  export LIB_HOME=/app/tomcat/webapps/ROOT/WEB-INF/lib/javac -d ../classes -cp $LIB_HOME\*:. Transfer2Application.javajava -cp $LIB_HOME\*:. Transfer2Application*/
public class Transfer2Application
{public static void main(String[] args){try {System.out.println("##################  hello world! 1 ");//初始化Hbase信息initHbase();} catch (Exception e) {e.printStackTrace();}}/*** 系统启动时初始化Hbase连接信息，包括kerberos认证** @throws Exception*/private static void initHbase() throws Exception{System.out.println("##################  hello world! initHbase  ");System.getProperties().setProperty("hadoop.home.dir", "/app/tomcat/temp/hbase");System.setProperty("java.security.krb5.conf", "/app/tomcat/krb5.conf");Configuration conf = HBaseConfiguration.create();conf.set("hbase.keytab.file", "/app/tomcat/gz**.app.keytab");conf.set("hbase.kerberos.principal", "gz***/gz**-***.dcs.com@DCS.COM");UserProvider userProvider = UserProvider.instantiate(conf);// login the server principal (if using secure Hadoop)if (userProvider.isHadoopSecurityEnabled() && userProvider.isHBaseSecurityEnabled()){String machineName = Strings.domainNamePointerToHostName(DNS.getDefaultHost(conf.get( "hbase.rest.dns.interface", "default"),conf.get( "hbase.rest.dns.nameserver", "default")));String keytabFilename = conf.get( "hbase.keytab.file" );Preconditions.checkArgument(keytabFilename != null && !keytabFilename.isEmpty(),"hbase.keytab.file"+ " should be set if security is enabled");String principalConfig = conf.get( "hbase.kerberos.principal" );Preconditions.checkArgument(principalConfig != null && !principalConfig.isEmpty(),"hbase.kerberos.principal" + " should be set if security is enabled");userProvider.login( "hbase.keytab.file" , "hbase.kerberos.principal", machineName);System.out.println("########## login success! #######");}else{System.out.println("不具备登陆条件！");System.out.println("userProvider.isHadoopSecurityEnabled() ："+userProvider.isHadoopSecurityEnabled() );System.out.println("userProvider.isHBaseSecurityEnabled()："+userProvider.isHBaseSecurityEnabled());}}
}

POD上手撕代码的几条重要命令

# 应用pod上 lib目录路径，用于设置java classpath
export LIB_HOME=/app/tomcat/webapps/ROOT/WEB-INF/lib/
# 进入src目录并创建主类源文件
cd src
# 编译主类，并将lib目录下所有jar加入到classpath中
javac -d ../classes -cp $LIB_HOME\*:. Transfer2Application.java
# 进入classes目录
cd ../classes
# 运行二进制文件
java -cp $LIB_HOME\*:. Transfer2Application

A：没有成功加载hadoop动态库。从官方下载动态库并拷贝到动态库路径中即可。官方动态库下载地址：https://archive.apache.org/dist/hadoop/common/hadoop-2.7.1/hadoop-2.7.1.tar.gz

动态库文件路径：hadoop-2.7.1/lib/native

把这个目录所有文件拷贝到：/usr/lib 目录下 ，其为日志中提示的java.library.path的目录之一
注意：

     默认拷贝到lib下的文件不包含可直接使用的动态库（不会被加载），原因是默认是的文件链接，拷贝进去就丢失了。需要重新创建文件链接、或做二次拷贝、或是重命名

Q4:运行时报各种网络不通，包括不能访问kerberos服务

A：打通网络端口，开通hbase服务端主机端口，清单如下（实际大家的端口号可能不一致，但都有）：

端口号客户端是否必需打通该端口端口说明
8090资源管理页面端口
50470https节点访问端口
8485√共享目录端口
8020√rpc端口
50070√节点http访问端口（需要打通）
2181√zookeeper服务端口（需要打通）
8088√RM资源管理器http端口
16000√master服务端口
3888√主zookeeper端口
16010√master 信息端口
13562√mapreduce分片服务端口
2049nfs文件系统访问端口
16100多播端口
8080√服务rest端口
16020√RS区域服务端口
21ftp端口
4242nfs挂载端口
88√KDC通信端口
80√Kerberos服务端口
749√这是一个可选的端口，主要用于Kerberos的TCP服
800这些端口用于Kerberos的KDC之间的通信，特别是在设置了跨多个KDC的环境时
801这些端口用于Kerberos的KDC之间的通信，特别是在设置了跨多个KDC的环境时
464√这是Kpasswd服务的端口，用于更改Kerberos用户的密码。
750一些实现可能使用这个端口来支持Kpasswd服务的额外功能。
636如果Kerberos配置为使用LDAP over SSL（LDAPS），则LDAPS服务通常运行在这个端口上。虽然这不是Kerberos原生的一部分，但它常被用于管理Kerberos用户账户和策略。
9090Thrift接口端口，支持非Java客户端访问HBase
60020RegionServer工作节点端口，处理客户端读写请求
2888集群内机器通讯使用，Leader监听此端口
