1、下載kudu依賴： yum -y install cyrus-sasl-plain ntp
2、下載kudu rpm包：
3、kudu安裝部署分布：
|
機器
|
服務
|
| cdh01 |
kudu-master，kudu-tserver
|
|
cdh02
|
kudu-master，kudu-tserver
|
|
cdh03
|
kudu-master，kudu-tserver
|
4、進入目錄：/etc/kudu/conf
修改master.gflagfile文件如下：
# Do not modify these two lines. If you wish to change these variables, # modify them in /etc/default/kudu-master. ## Comma-separated list of the RPC addresses belonging to all Masters in this cluster. ## NOTE: if not specified, configures a non-replicated Master. --fromenv=rpc_bind_addresses --fromenv=log_dir --fs_wal_dir=/var/lib/kudu/master --fs_data_dirs=/var/lib/kudu/master --master_addresses=cdh02:7051,cdh03:7051 ## You can avoid the dependency on ntpd by running Kudu with --use-hybrid-clock=false ## This is not recommended for production environment. ## NOTE: If you run without hybrid time the tablet history GC will not work. ## Therefore when you delete or update a row the history of that data will be kept ## forever. Eventually you may run out of disk space. #--use_hybrid_clock=false
修改tserver.gflagfile文件如下：
# Do not modify these two lines. If you wish to change these variables, # modify them in /etc/default/kudu-tserver. --fromenv=rpc_bind_addresses --fromenv=log_dir --fs_wal_dir=/var/lib/kudu/tserver --fs_data_dirs=/var/lib/kudu/tserver --tserver_master_addrs=node02:7051,node03:7051
5、上面兩個文件修改好之后分發到上述三台機器
啟動方式：進入/etc/init.d目錄：
service kudu-master restart
service kudu-tserver restart
6、啟動后在/var/log/kudu目錄進行日志的查看
啟動成功在后台查看端口：
master：8051
tserver：8050
進入瀏覽器進行IP:端口 驗證kudu服務是否正常
kudu常見報錯，摘自：
整理如下：
第一種報錯：
Log file created at: 2018/04/02 10:40:33 Running on machine: mrj001 Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg 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.
報錯分析：
至少需要配置兩個master，但是只配置了一個
報錯處理：
kudu-master支持多master備份機制，所以配置時需注意； vi /etc/kudu/kudu-master 注釋掉--master-addresses 該參數配置為master節點以及ip列表，不指定默認為單master節點；如果指定了該配置，但是只有一個master節點就會報錯；
第二種報錯：
Log file created at: 2018/04/02 10:46:39
Running on machine: mrj001
Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
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)
報錯分析：
kudu-tserver啟動報錯，對目錄/soft/kudu/data/data/block_manager_instance不能夠進行鎖定
第三種報錯：
Log file created at: 2018/04/06 16:13:39
Running on machine: mrj001
Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
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
報錯分析：
kudu在啟動之前必須保證各個服務器ntp一致，當各個table server不一致時會導致此報錯；
解決辦法：
查看ntpd服務是否開啟：service ntpd status
查看ntpd服務是否已經同步：ntpstat
如果沒有安裝ntp服務，請參照本人所寫博客：https://blog.csdn.net/m0_38003171/article/details/79789557
第四種報錯：
Log file created at: 2018/04/07 13:24:52
Running on machine: mrj001
Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
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)
報錯分析：
經過分析報錯可以得出：/soft/kudu/master/data/目錄下沒有創建文件的權限，同時kudu在啟動的時候默認是使用kudu用戶進行創建，所以要確定kudu用戶能夠對該文件夾下面的所有目錄進行管理
報錯處理：
在沒有權限的目錄下面執行：chown -R kudu:kudu ./*,改變用戶組和用戶為kudu即可解決
第五種報錯：
Log file created at: 2018/04/07 13:37:05
Running on machine: mrj001
Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
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
報錯分析：
/soft/kudu/tserver/wal包含不符合規則的空白
報錯處理：
這個報錯是因為tserver配置文件中沒有指定master地址造成的； 檢查/etc/kudu/conf/tserver.gflagfile配置文件，在該配置文件中添加：--tserver_master_addrs=mrj001:7051 注意：mrj001為主機名
