1、下载kudu依赖： yum -y install cyrus-sasl-plain ntp
 
2、下载kudu rpm包：
 
3、kudu安装部署分布：

机器
服务
cdh01
kudu-master，kudu-tserver
cdh02
kudu-master，kudu-tserver
cdh03
kudu-master，kudu-tserver
 
4、进入目录：/etc/kudu/conf
修改master.gflagfile文件如下：
 
 

  1. # Do not modify these two lines. If you wish to change these variables,
  2. # modify them in /etc/default/kudu-master.
  3. ## Comma-separated list of the RPC addresses belonging to all Masters in this cluster.
  4. ## NOTE: if not specified, configures a non-replicated Master.
  5.  
  6. --fromenv=rpc_bind_addresses
  7. --fromenv=log_dir
  8. --fs_wal_dir=/var/lib/kudu/master
  9. --fs_data_dirs=/var/lib/kudu/master
  10. --master_addresses=cdh02:7051,cdh03:7051
  11.  
  12. ## You can avoid the dependency on ntpd by running Kudu with --use-hybrid-clock=false
  13. ## This is not recommended for production environment.
  14. ## NOTE: If you run without hybrid time the tablet history GC will not work.
  15. ## Therefore when you delete or update a row the history of that data will be kept
  16. ## forever. Eventually you may run out of disk space.
  17. #--use_hybrid_clock=false
 
修改tserver.gflagfile文件如下：
  1. # Do not modify these two lines. If you wish to change these variables,
  2. # modify them in /etc/default/kudu-tserver.
  3. --fromenv=rpc_bind_addresses
  4. --fromenv=log_dir
  5. --fs_wal_dir=/var/lib/kudu/tserver
  6. --fs_data_dirs=/var/lib/kudu/tserver
  7. --tserver_master_addrs=node02:7051,node03:7051

 

5、上面两个文件修改好之后分发到上述三台机器

 
启动方式：进入/etc/init.d目录：
  1. service kudu-master restart
  3. service kudu-tserver restart

 6、启动后在/var/log/kudu目录进行日志的查看

启动成功在后台查看端口：
master：8051
tserver：8050
进入浏览器进行IP:端口 验证kudu服务是否正常
 
kudu常见报错，摘自：

整理如下：
 
第一种报错：
  1. Log file created at: 2018/04/02 10:40:33
  2. Running on machine: mrj001
  3. Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
  4. F0402 10:40:33.091943 51977 master_options.cc:46] At least 2 masters are required for a distributed config, but master_addresses flag ('192.168.137.6') only specifies 1 masters.

 

报错分析：

    至少需要配置两个master，但是只配置了一个

报错处理：

  1.     kudu-master支持多master备份机制，所以配置时需注意；
  3.     vi /etc/kudu/kudu-master
  5.     注释掉--master-addresses 
  7.     该参数配置为master节点以及ip列表，不指定默认为单master节点；如果指定了该配置，但是只有一个master节点就会报错；

 

 
 第二种报错：
  1. Log file created at: 2018/04/02 10:46:39
  2. Running on machine: mrj001
  3. Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
  4. F0402 10:46:39.101296 52137 tablet_server_main.cc:72] Check failed: _s.ok() Bad status: IO error: Failed to load FS layout: Could not lock /soft/kudu/data/data/block_manager_instance: Could not lock /soft/kudu/data/data/block_manager_instance: lock /soft/kudu/data/data/block_manager_instance: Resource temporarily unavailable (error 11)

报错分析：

    

  1. kudu-tserver启动报错，对目录/soft/kudu/data/data/block_manager_instance不能够进行锁定

 

 
 
 第三种报错：
  1. Log file created at: 2018/04/06 16:13:39
  2. Running on machine: mrj001
  3. Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
  5. F0406 16:13:39.828665  2572 master_main.cc:68] Check failed: _s.ok() Bad status: Service unavailable: Cannot initialize clock: Error reading clock. Clock considered unsynchronized

 

报错分析：

  1. kudu在启动之前必须保证各个服务器ntp一致，当各个table server不一致时会导致此报错；

解决办法：

  1. 查看ntpd服务是否开启：service ntpd status
  3. 查看ntpd服务是否已经同步：ntpstat
  5. 如果没有安装ntp服务，请参照本人所写博客：https://blog.csdn.net/m0_38003171/article/details/79789557

 

 
 第四种报错：
  1. Log file created at: 2018/04/07 13:24:52
  2. Running on machine: mrj001
  3. Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
  5. F0407 13:24:52.627974  5771 master_main.cc:68] Check failed: _s.ok() Bad status: IO error: Could not create new FS layout: Unable to write instance metadata: Call to mkstemp() failed on name template /soft/kudu/master/data/instance.kudutmp.XXXXXX: Permission denied (error 13)

 

报错分析：

  1. 经过分析报错可以得出：/soft/kudu/master/data/目录下没有创建文件的权限，同时kudu在启动的时候默认是使用kudu用户进行创建，所以要确定kudu用户能够对该文件夹下面的所有目录进行管理

 

报错处理：

  1. 在没有权限的目录下面执行：chown -R kudu:kudu ./*,改变用户组和用户为kudu即可解决

 

第五种报错：

  1. Log file created at: 2018/04/07 13:37:05
  2. Running on machine: mrj001
  3. Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
  5. F0407 13:37:05.960657  5931 tablet_server_main.cc:72] Check failed: _s.ok() Bad status: IO error: Failed to load FS layout: Filesystem root /soft/kudu/tserver/wal                                                                                                   contains illegal whitespace

报错分析：

  1. /soft/kudu/tserver/wal包含不符合规则的空白

 

报错处理：

  1. 这个报错是因为tserver配置文件中没有指定master地址造成的；
  3. 检查/etc/kudu/conf/tserver.gflagfile配置文件，在该配置文件中添加：--tserver_master_addrs=mrj001:7051
  5. 注意：mrj001为主机名
