0. root권한으로 설치하고 실제 사용은 hadoop게정이 하는 경우임.

1. hive 다운로드및 설치할 위치에 업로드

http://mirror.apache-kr.org/hive/

* apache-hive-2.0.1-bin.tar.gz를 선택하여 다운로드하여 winscp등를 이용하여 업로드한다.

2. 압축풀기

  - tar xvfz apache-hive-2.0.1-bin.tar.gz

3. 링크 걸기

  - ln -s apache-hive-2.0.1-bin hive

4. /etc/profile에 아래의 내용을 추가함(hive가 설치되는 모든 서버에서 실행함)

     export HIVE_HOME=$HOME/hive
     export PATH=$PATH:$HIVE_HOME/bin

 * source /etc/profile로 반영함

 * hadoop이 설치되어 있고 HADOOP_HOME의 환경변수값이 설정되어 있지 않으면

    export HADOOP_HOME=<hadoop-install-dir>를 반드시 설정해줘야 함.

5. conf파일 생성

  conf/*.template파일을 복사하여 각각의 설정파일을 만든다.

  cp hive-env.sh.template hive-env.sh

  cp hive-exec-log4j2.properties.template hive-exec-log4j2.properties

  cp hive-log4j2.properties.template hive-log4j2.properties

  cp hive-default.xml.template hive-site.xml (파일의 이름이 hive-default.xml.template에서hive-site.xml로 변경됨)

  cp beeline-log4j2.properties.template beeline-log4j2.properties

6. hive에서 사용할 HDFS에 디렉토리 구성및 권한부여 

hadoop fs -mkdir /tmp

hadoop fs -mkdir /user/hive
hadoop fs -mkdir /user/hive/warehouse

hadoop fs -chmod g+w /tmp
hadoop fs -chmod g+w /user/hive/warehouse

hadoop fs -chown hadoop:hadoop /user/hive

hadoop fs -chown hadoop:hadoop /user/hive/warehouse

7. mysql 혹은 mariadb설치(필요시, 최초한번)

 root@master:/usr/local# apt-get install mysql-server

(404오류가발생시 https://www.gooper.com/ss/index.php?mid=bigdata&category=2772&document_srl=2995를 참조하여 조치후 설치한다)

8. db생성(mysql의 db생성등의 권한이 있는 계정으로 실행)

mysql> create database hive_metastore_db;

Query OK, 1 row affected (0.00 sec)

9. 사용자 생성및 원격 접속 가능하도록 설정

가. mysql> grant all privileges on *.* to 'hive'@'localhost' identified by '패스워드' with grant option;

Query OK, 0 rows affected (0.00 sec)

나. mysql>grant all privileges on *.* to 'hive'@'%' identified by '패스워드' with grant option;

다. grant all privileges on hive_metastore_db.* to 'hive'@'%' identified by '패스워드';

* 확인

mysql> select host from mysql.user where user='hive';
+-----------+
| host      |
+-----------+
| %         |
| localhost |
+-----------+
2 rows in set (0.00 sec)

10. 테이블 생성 스크립트 원격 실행($HOmE/hive/scripts/metastore/upgrade밑에 있는 스크립트를 이용한다)

$HOME/hive/scripts/metastore/upgrade/mysql>

mysql --host=so-db1 --port=3306  -u root -p패스워드 hive_metastore_db < hive-schema-2.0.0.mysql.sql 

다른 방법으로 아래와 같이 사용할 수 있음(13번 항목이 설정된 다음에 실행가능함)

* ./bin/schematool -initSchema -dbType mysql -verbose 을 사용하여 metastore의 초기화를 수행할 수 있음

* ./bin/schematool -info -dbType mysql을 사용하면 설정된 정보를 확인할 수 있음

11. mysql connector를 다운로드하여 $HIVE_HOME/lib에 복사

   (http://www.mysql.com/downloads/connector/j/에서 다운로드하여 압축해제후 mariadb-java-client-1.5.9.jar를 $HIVE_HOME/lib에 복사)

12. $HIVE_HOME/conf/hive-env.sh에서 hadoop위치를 지정해준다.

# Set HADOOP_HOME to point to a specific hadoop install directory

# HADOOP_HOME=${bin}/../../hadoop

HADOOP_HOME=$HOME/hadoop

13. $HIVE_HOME/conf의 hive-site.xml에 아래를 추가 혹은 변경한다.

<configuration>

<property>

  <name>javax.jdo.option.ConnectionURL</name>

  <value>jdbc:mysql://localhost:3306/hive_metastore_db?createDatabaseIfNotExist=true</value>

  <!-- value>/tmp/hive</value -->

  <value>/tmp/hive-${user.name}</value>

<name>hive.exec.local.scratchdir</name>

13-1. Table Lock Manager활성화를 위한 설정(설정하지 않으면 동일한 테이블에 동시에 쿼리가 수행될때 데이타가 오염될 수 있음)

  <property>

    <name>hive.support.concurrency</name>

    <value>true</value>

    <description>

      1. Read/write locks - when hive.lock.manager is set to

      org.apache.hadoop.hive.ql.lockmgr.zookeeper.ZooKeeperHiveLockManager,

      2. When HiveServer2 supports service discovery via Zookeeper.

      3. For delegation token storage if zookeeper store is used, if

      hive.cluster.delegation.token.store.zookeeper.connectString is not set

      4. LLAP daemon registry service

    </description>

  </property>

14. hadoop-env.sh 끝에 아래의 내용을 추가하여 hive관련 lib및 conf를 hadoop이 인식할 수 있도록 한다.

가. export HADOOP_CLASSPATH에 $HIVE_HOME/conf:$HIVE_HOME/lib를 추가함

나. 파일끝에 아래를 추가하여 hadoop이 hive를 인식할 수 있도록함

for f in ${HIVE_HOME}/lib/*.jar; do
   HADOOP_CLASSPATH=${HADOOP_CLASSPATH}:$f;
done

15. hive metastore실행

   : hive metastore서버 시작(hive가 설치된 master에서 실행)

    nohup bin/hive --service metastore &

  *오류시 참조 : https://www.gooper.com/ss/index.php?mid=bigdata&category=2777&document_srl=3393

  *확인 : jps m

  118506 RunJar /opt/bin/hadoop/hive/lib/hive-service-2.0.1.jar org.apache.hadoop.hive.metastore.HiveMetaStore

16.  hiveserver2실행(JDBC로 접근할 수 있도록 서버를 띄워준다)

   *확인3 : http://sda1:10002/hiveserver2.jsp

17. beeline실행(JDBC를 이용하여 hiveserver2에 접근하는 client프로그램)

hiveserver2에 접근하기 위해서 "bin/beeline -u jdbc:hive2://sda1:10000"을 실행한다.
