1. 概述

本文首先會簡單介紹Kylin的安裝配置，而後介紹啓用Kerberos的CDH集羣中如何部署及使用Kylin。html

Apache Kylin™是一個開源的分佈式分析引擎，提供Hadoop/Spark之上的SQL查詢接口及多維分析（OLAP）能力以支持超大規模數據，最初由eBay Inc. 開發並貢獻至開源社區。它能在亞秒內查詢巨大的Hive表。node

1.2 環境說明

CDH版本：5.11.2
Linux版本：7.4.1708
Docker版本：Docker version 18.06.0-ce
JDK版本：1.8
操做用戶：root

2.Kylin安裝配置

2.1 安裝

此處以Kylin 2.0.0版本爲例。
社區版Kylin地址：https://archive.apache.org/dist/kylin/git

[root@node-3 ~]# cd /usr/local/src/
[root@node-3 src]# wget https://archive.apache.org/dist/kylin/apache-kylin-2.0.0/apache-kylin-2.0.0-bin-cdh57.tar.gz
[root@node-3 src]# tar xf apache-kylin-2.0.0-bin-cdh57.tar.gz 
[root@node-3 src]# cp -a apache-kylin-2.0.0-bin /usr/local/
[root@node-3 src]# ln -s /usr/local/apache-kylin-2.0.0-bin /usr/local/kylin

2.2 環境配置

export BASE_PATH_BIG=/opt/cloudera/parcels/CDH/lib

#added by Hbase
export HBASE_HOME=$BASE_PATH_BIG/hbase

#added by HCat
export HCAT_HOME=/opt/cloudera/parcels/CDH/lib/hive-hcatalog/share/hcatalog

#added by Kylin
export KYLIN_HOME=/usr/local/kylin
export PATH=$HBASE_HOME/bin:$PATH

而後執行source /etc/profile生效。github

2.3 Kylin配置

編輯/usr/local/kylin/conf/kylin.properites文件，新增如下配置：web

Kylin2.0+版本配置的名稱有變化，具體參考：https://github.com/apache/kylin/blob/2.0.x/core-common/src/main/resources/kylin-backward-compatibility.propertiesshell

## 修改配置（替換地址）
kylin.rest.servers=192.168.100.102:7070

## 新增配置
kylin.job.jar=/usr/local/apache-kylin-2.0.0-bin/lib/kylin-job-2.0.0.jar
kylin.coprocessor.local.jar=/usr/local/apache-kylin-2.0.0-bin/lib/kylin-coprocessor-2.0.0.jar
## 替換地址
kylin.job.yarn.app.rest.check.status.url=http://cdh-node-2:8088/ws/v1/cluster/apps/${job_id}?anonymous=true
kylin.job.mr.lib.dir=/opt/cloudera/parcels/CDH-5.11.2-1.cdh5.11.2.p0.4/lib/sentry/lib

配置說明：

kylin.rest.servers：kylin實例服務器列表，注意：不包括以job模式運行的服務器實例！apache
kylin.job.jar：MR jobs依賴
kylin.coprocessor.local.jar：Hbase協同處理依賴，用於提升性能。
kylin.job.yarn.app.rest.check.status.url：yarn工做區
kylin.job.mr.lib.dir：Hive/Hbase依賴目錄。（在沒有安裝Hive/Hbase的節點上構建Cube會由於找不到依賴報ClassNotFoundException錯誤，須要此配置。具體參考這邊博文《上傳Kylin MR依賴》)。bash

更多配置請參考官網配置指南。服務器

2.4 建立用戶

在每一個節點建立Kylin用戶app

useradd kylin

3. Kerberos配置

3.1 建立kylin帳號

在Kerberos server上建立kylin帳號：

[root@cdh-node-1 /]# kadmin.local
Authenticating as principal admin/admin@HWINFO.COM with password.
kadmin.local:  addprinc kylin
WARNING: no policy specified for kylin@HWINFO.COM; defaulting to no policy
Enter password for principal "kylin@HWINFO.COM":
Re-enter password for principal "kylin@HWINFO.COM":
add_principal: Principal or policy already exists while creating "kylin@HWINFO.COM".
kadmin.local:

3.2 生成keytab文件

生成kylin帳號keytab文件：

xst -norandkey -k klin.keytab kylin@HWINFO.COM

將kylin.keytab複製到每一個kylin節點上。

3.3 定時刷新kt

在kylin節點上配置定時任務進行kinit命令：

kinit -k -t /root/kylin.keytab kylin@HWINFO.COM

添加定時任務,這裏設置天天凌晨1點執行一次，可根據kerberos的過時時間本身配置。

編寫shell腳本：

[root@cdh-node-2 security]# cat init_kt.sh
#!/bin/bash
kinit -kt ./kylin.keytab kylin@HWINFO.COM

添加定時任務：

[root@cdh-node-2 security]# crontab -e

# 添加如下內容
0 1 * * * root /home/security/init_kt.sh  > /tmp/kylin-ktinit.log 2>&1

# 查看定時任務
[root@cdh-node-2 security]# crontab -l
0 1 * * * root /home/security/init_kt.sh  > /tmp/kylin-ktinit.log 2>&1

3.4 添加Hive權限

登陸Hive
使用擁有操做hive權限的kerberos帳戶登陸beeline：

[root@cdh-node-3 hive]# beeline -u 'jdbc:hive2://cdh-node-3:10000/default;principal=hive/cdh-node-3@HWINFO.COM'
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0
scan complete in 2ms
Connecting to jdbc:hive2://cdh-node-3:10000/default;principal=hive/cdh-node-3@HWINFO.COM
Connected to: Apache Hive (version 1.1.0-cdh5.11.2)
Driver: Hive JDBC (version 1.1.0-cdh5.11.2)
Transaction isolation: TRANSACTION_REPEATABLE_READ
Beeline version 1.1.0-cdh5.11.2 by Apache Hive
0: jdbc:hive2://cdh-node-3:10000/default>

添加kylin權限
將admin角色權限賦予kylin：

0: jdbc:hive2://cdh-node-3:10000/default> grant role admin to user kylin;
INFO  : Compiling command(queryId=hive_20180914174141_6359e1a1-251f-4116-b646-0aa9f55dcfa8): grant role admin to user leili
INFO  : Semantic Analysis Completed
INFO  : Returning Hive schema: Schema(fieldSchemas:null, properties:null)
INFO  : Completed compiling command(queryId=hive_20180914174141_6359e1a1-251f-4116-b646-0aa9f55dcfa8); Time taken: 0.069 seconds
INFO  : Executing command(queryId=hive_20180914174141_6359e1a1-251f-4116-b646-0aa9f55dcfa8): grant role admin to user leili
INFO  : Starting task [Stage-0:DDL] in serial mode

INFO  : OK
No rows affected (0.528 seconds)

3.5 添加Hbase權限

使用擁有操做hbase權限的kerberos帳戶登陸hbase shell：

[root@cdh-node-3 hive]# hbase shell
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release
18/09/14 17:44:40 INFO Configuration.deprecation: hadoop.native.lib is deprecated. Instead, use io.native.lib.available
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 1.2.0-cdh5.11.2, rUnknown, Fri Aug 18 14:09:37 PDT 2017

給kylin用戶受權

base(main):001:0> grant 'kylin','RWXCA'
0 row(s) in 0.5830 seconds

切換到kylin用戶從新登陸hbase shell，測試一下：

hbase(main):001:0> whoami
kylin@HWINFO.COM (auth:KERBEROS)
    groups: kylin

hbase(main):002:0> create 'test', 'cf'
0 row(s) in 2.6930 seconds

=> Hbase::Table - test
hbase(main):003:0> list
TABLE
test
1 row(s) in 0.0310 seconds

3.6 執行Kylin檢查

[root@cdh-node-2 bin]# ./check-env.sh
Retrieving hadoop conf dir...
KYLIN_HOME is set to /usr/local/apache-kylin-2.0.0-bin

3.7 啓動kylin服務

先確認主機使用kerberos憑據爲kylin，再啓動：

[root@cdh-node-2 bin]# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: kylin@HWINFO.COM

Valid starting       Expires              Service principal
09/14/2018 17:48:28  09/15/2018 17:48:28  krbtgt/HWINFO.COM@HWINFO.COM
    renew until 09/21/2018 17:48:28
[root@cdh-node-2 bin]# ./kylin.sh start
Retrieving hadoop conf dir...
KYLIN_HOME is set to /usr/local/kylin
Retrieving hive dependency...
Retrieving hbase dependency...
Retrieving hadoop conf dir...
Retrieving kafka dependency...
Retrieving Spark dependency...
KYLIN_JVM_SETTINGS is -Xms1024M -Xmx4096M -Xss1024K -XX:MaxPermSize=128M -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:/usr/local/kylin/logs/kylin.gc.3982 -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=64M

A new Kylin instance is started by root. To stop it, run 'kylin.sh stop'
Check the log at /usr/local/kylin/logs/kylin.log
Web UI is at http://<hostname>:7070/kylin

4. 使用Kylin Sample測試

Kylin自己自帶了一個測試例子，建立流程以下：
執行sample.sh腳本，這個主要是建立kylin的project、model、cube以及相關的hive表等。

[root@cdh-node-2 bin]# ./sample.sh
Retrieving hadoop conf dir...
Retrieving hadoop conf dir...
KYLIN_HOME is set to /usr/local/kylin
Loading sample data into HDFS tmp path: /tmp/kylin/sample_cube/d

...

Sample cube is created successfully in project 'learn_kylin'.
Restart Kylin server or reload the metadata from web UI to see the change.

進入Kylin Web界面system - reload metadata
而後構建示例的cube，若是構建成功，而且能成功執行查詢命令，則表示整個配置所有完成。
